revelation in terms of imagery and soundstage
they hammer the Sonus Faber's!
found myself just sitting and listening to the music!
Powerful controlled sound that instantly gets your attention
midrange is clear with great vocal reproduction and the treble is faultless
crystal clear top end, with a massive and controlled midrange, and that superb bass
I prefer these to my Spendor A19 and better than my home demo of .....
music is so much more open & fluid
Ended up spending several hours listening to music I enjoyed it so much.
I had a quick go at writing a review. I won't post it yet just in case I think of anything else to add. Anyway here it is -
Over the years I have used a variety of different stereo amps, av receivers and speakers including Monitor Audio Bronze, Dali Ikon, Cambridge Audio and Dali Zensor. I have ended up swapping equipment on numerous occasions because I enjoy the process of trying different things out.
Recently I decided that I should try spending some more money and see what something a little more expensive is like, so I sold some equipment and with the money from that bought an Abrahamsen amp and then started pondering what speakers I could use with them.
The number of speakers available is somewhat overwhelming and it makes choosing the right speaker quite hard, although in the end given the budget I had it was narrowed down to a few choices and I decided to go with the IPL Acoustics SM2 speakers.
I was intrigued by what DIY speakers would be like (probably the main reason for buying them) and spent some time reading what others had said about IPL speakers online before emailing Colin and asking questions about them. Once I was satisified with everything I placed an order and was told they would be ready within around 5 weeks. Of course I wasn’t able to hear them and it’s always a risk to buy speakers without hearing them but it was a risk I was prepared to take.
Colin provided regular updates along the way with plenty of photos of the speakers being built and a video. It was a nice touch and I found it fascinating to see how the speakers were put together.
Once the speakers were delivered I unpacked them and set them on their stands. They are heavy, feel really solid and the build quality is very high. The santos rosewood veneer looks great and is really well polished.To my eyes it looks like there’s been a lot of care and attention in building these speakers and the end result is great and certainly lives up to expectations. I think the finish of the speakers is incredibly close to what you would expect when buying from the big commercial brands. One final point about the build quality is the grills - they have been set up with magnets so they attach to the front of the speaker very easily and I even quite like the iQ Speakers logo. I normally don’t like badges but in this case it’s small, discreet and not shiny so turned out ideal.
Now onto the sound. I listened to several different CDs including artists like Karunesh, Craig Armstrong, Lesiem, Ane Brune, Dunedin Consort, Jackson Browne, First Aid Kit, Israel Nash, Sleepthief, Thea Gilmore, Amethystium, Dire Straits and Mike Oldfield. So lots of different kinds of music to hear. In the short time I’ve spent with them have been really impressed. It’s been a delight to sit back and listen to all this music. Everything just seems right and balanced regardless of what music I’m playing. There’s also a great sense of scale and depth when the volume goes up. Also, the bass was something that was a slight concern prior to trying them out, but it’s turned out fine and seems controlled and powerful without booming which I did experience with some of my other speakers. I do find it hard to descibe how speakers sound but the main thing is I’m delighted with these speakers and believe the money has been well spent.
sorry to have taken so long with this feedback but I hope you can use it.
I initially met Colin when I bought an Abrahamsen V40 UP amplifier off him and went round to his house to audition it. I was so impressed with the amp I bought it there and then. He was using a pair of IPL S2TLK which he had built and, on listening to them I was absolutely blown away. I asked to borrow them for a listen at home and Colin was willing to oblige in his usual helpful way, so I brought them to my home and set them up. I had at the time a pair of Sonus Faber Venere 2.5s which I had been using for about a year and up until that point was very pleased with them-up until listening to the IPLs in my living room that is. The IPLs were clearer in the bid range, the treble was sweet and precise and the base was lower, tighter and quicker, lots lower. I was so taken with them that I ordered a pair which I have now had for about a month and the more I listen to them, the more I like em. The finish is exactly as ordered and to a high quality (even my partner likes them), and the sound continues to amaze me. I have not heard anything to approach these even at two or three times the price or more. Needless to say I am very impressed and after many years of being a HiFi upgrader I really don’t know where I would go next to find anything that sounded better without spending silly money. These are fantastic speakers.
Hi Colin, if this is of any use you leave my surname out please…..Cheers. How are you doing, hows the shed, the latest speaker build, and the red stripe?
I'm not good at describing the sound from the speakers but I can tell you I am impressed and very happy.
My old TDL's Studio One although being the smallest speaker in the Studio line produced too much bass for my small room, too much boom.
Well the IPL's have solved that problem. The bass is well defined not boomy, they don't go as low as the TDL but the the bass is still there but
much better controlled and it's very dynamic.
The ribon tweeter produces a very clear but not harsh sound and is very transparent (reminds me of the Magneplanars I had many years ago).
Not only I can now hear details which were barely audible in the old speakers I can also hear things which were no there before, they are very revealing.
Overall, I am very happy with the way they sound at the moment and I know they will improve further with time.
So, the speakers look gorgeous, the sound is impressive, I am a very happy man!
Review from Colin Crawford owner Dale Forty Piano's, Music Producer, HiFi enthusiast and collector.
I have just spent a week in the company of these great little floor standing speakers (M1), and they are truly a revelation in terms of imagery and soundstage. Bass is good and solid, and there’s a real illusion of artists being ‘in the room’ especially on acoustic guitar and female vocals. They were best in my installation when the volume is at higher levels, not because of inefficiency, (they’re not!) but because the soundstage appears to open up a bit more at higher volumes. This may be partly because this pair is only barely run-in, or a function of the small room size which is less than ideal. They were particularly sweet sounding on the end of a pair of original Quad valve amplifiers, but in general, listening of digital sources was via an Arcam rDAC, and analogue was a Garrard 401 with Denon DL103 through a Naim 32.5/HiCAP/160. A bargain at the price!
Paul demoed and bought my first pair of M1TLm's in Piano Black. Hi Colin, Just a quickie to say that I've set the speakers up & had about a 1 hour road test & even with my exposure amps they hammer the Sonus Faber's! The music is so much more open & fluid than before. Oh & my girlfriend loves them! I'll let you know over the next couple of days about the amp but I'm 95% sure I'll get it from you. Thanks so much for all the help & advice & it's been a pleasure meeting you. Cheers, Paul In Another text he sent he says "i have not stopped grinning since I heard the first few bars Saturday evening" Paul also bought the Abrahamsen V2.0 UP.
Also review left on WHF
This is my 1st post on any forum (please go easy on me!) but I felt the need to share my Hifi joy of the last few days. I went round to iQ Speakers to demo the Abrahamsen V2.0UP amp. It was running alongside his beautiful iQ speakers built IPL Acoustics M1TLm speakers. From the 1st few bars I was grinning from ear to ear. The sound quality of both the amp & speakers were absolutely amazing. The timing, clarity & openness were truly stunning.
2 hours later I was still grinning like the proverbial Cheshire Cat. I had no intention of getting rid of my beloved Sonus Faber's but was so blown away by the Abrahamsen amp & IPL Speakers, I ended up purchasing both from iQ.
It's not only the sound quality of the amp & speakers which is outstanding it is the build quality as well. I would think you would have to spend at least 4 times the amount these cost to get near to the same level of performance/quality.
What iQ has done with the IPL speakers is taken a premium sounding pair of speakers & given them the luxurious build & finish they deserve.
Coupled with the fantastic chap iQ is, this has been my most pleasurable Hifi experience ever.
I can't recommend highly enough iQ Speakers, the Abrahamsen amp & the speakers. This equipment has got to be heard to be believed & in my opinion is a absolute bargain.
Since setting up my new equipment I can't stop listening to it!

Dear Colin,Nice to see somebody is building these brilliant speakers. I have had a pail of S5TL for a while now and they are brilliant. They have seen off some very expensive opposition including a set of B&W Nautilus’s.
If anybody needs a listen they are welcome. However mine are made of Birch Ply which I feel is far superior sonically to MDF
The folowing reviews are from IPL Acoustics customers
Mr A Slopecki writes regarding M1tlm Ribbons, Have just turned the speakers on for the first time. They are replacing mission speakers that were top of the range when bought. I am using Naim pre and power amplifiers with Naim CD player,-Bottom of the range. I know they still have to run in but even given that they sound fantastic. So pleased Just need to finish the grilles and bottom port.
Mr D Reid writes regarding M1tlm Ribbon, Many thanks for your help and supplying me with this amazing kit, I am absolutely chuffed to bits with the M1TLMs! There is a massive improvement over my previous floor standing speakers. I will be listening to allot more music again now!
Mr DM Buckland writes ;-Happy New Year . This is just a quick message to say how thrilled I am with the M1tls they are absolutely fantastic!. My dad can not stop listening to them! Hope you had a great Christmas and keep up the good work with the speakers.
Mr C Duff writes regarding S2tlP Ribbons, You may remember I finally bought the S2TLP Kit and after running them in for a few weeks I just wanted to tell you how pleased I am with them. I had originally intended to run them off a Denon system to replace a pair of Wharfedale 802.3s but it quickly became apparent that they are much to good for that setup . So off to the loft to retrieve my mothballed Quad Kit and try again. This proved to be a much better match but also reminded me the Quads were in need of a service. This has now been done and the results are just wonderful. I had been in the process of archiving my Vinyl collection but this process has come to a halt as I have found myself just sitting and listening to the music! . Many years ago I owned a pair of IMF Domestic Monitors which I was forced to sell for reasons of space. For the first time in nearly 30 years I can hear proper bass but with much improved mid/treble. A friend of mine who still runs a pair of IMF RSPM 4s thought very highly of the S2tlps remarking on both the extension and the clarity in the bass and the beautiful transparency of the ribbon tweeter, and she is not easily impressed. One day space permitting Id love to build the S5tl.
Mr A Rowe writes regarding S2TLP Ribbons, Just a quick note to let you know that I finished my S2tl kit a couple of months ago, and I am very pleased with the results. The extra speed on transients from the Ribbon tweeters is everything that I was hoping for, and in every respect they are a worthwhile upgrade on my much loved but now rather elderly M3tl speakers (Morel bass units). Thanks again for designing and producing fine kits- a real example of high -end performance for a relatively low-end budget.
Mr J McWilliams writes regarding S2TLP Ribbons: Wow and Wow! The first is for the left speaker and the second is for the right speaker. I have completed the speakers and tried them. Having not heard them prior to purchasing the kit I was relying on what I had read on the internet. I can say I am not disappointed in any way. Even my wife likes them - and she is very picky. I will spend some time listening to them and tweaking them, But I am not in a big hurry to experiment as I want to give them some time to settle in and for my ears to adjust.
Mr M Laister writes regarding S2TLP Ribbons, I bought a pair of S2TLP s speakers from you in December 2014, They are marvellous They went together very well, and the sound they make is I think the best I have ever heard, They are more enjoyable to listen to than my ---805s and I think they beat the 801s I used to own too (I have never had a room big enough for them) Your advice was spot on- The S4s would have overwhelmed my rather crowded 12x13ft room. The S2s are a great match.
Mr J Morton writes regarding S2tlP Ribbons; Well the speakers are completed and I feel compelled to write and tell you just how impressed I am with them. I spent months considering various speakers up to £2500. The music I love is techno/electronic dance/experimental stuff loud, but my room is not huge. The S2tlp Ribbon speakers are frankly amazing. Astonishingly good low end frequency response, but the bass is tight and controlled and not booming . Mids are great, hi-hats beautiful and crisp at the top. Close your eyes and the speakers just disappear. Not too warm, not too analytical- no speaker fatigue at all even after prolonged listening. I was kind of preparing myself to be underwhelmed as I built everything up, but far from it- they exceed my expectations. Source kit is turntable or streamed FLAC files via Audiolab 8200CDQ combined CD, pre-amp, DAC, and class D Audio 400wpc (into 8 ohms) power amp. Thank you very much for an exceptional piece of kit.
Mr s Bunting writes ; The S2TLMs sound fantastic; I finished your kit last Friday and have had a very nice weekend listening to my record collection and hearing things I had never heard before. Even my wife is impressed at how good they sound
Mr. Sullivan Twyford writes; having purchased an M3tl kit from you last Christmas , I have now lived with the completed speaker for several months. The accuracy with which the panels were cut and the clear instructions made the speakers a joy to construct. The end result was quite astounding and never ceases to raise comment from all who hear them. Once it was found they were built on the dinning table and cost under £300 the reaction is disbelief. .Even my wife approves!
Mr Stuart Parkins (China) writes; A short note to express my complete satisfaction with all the speakers, I finished the S3tlm Ribbons,M3Ms,M3M centre, and SW4, (probably the first set of speakers to be made in a converted barn in a tiny village south of Nanching). After critically listening to a wide variety of my favourite CDs (high quality amp and IPL recommended cables) I am 150% satisfied with the sound in every way, Moreover the proportions of the cabinets (varnished, dark brown veneer) are aesthetically very pleasing. Excellent value for money
Mr G Coleman Writes regarding M3M Ribbons; Just dropping you a line to say thanks for supplying an absolute cracking speaker kit, I have just completed them as my wife would not let me have the electronic components until Xmas. They have not had much chance to settle in yet but the quality is outstanding. A joy to put together and a bigger joy to listen to. I will definitely be purchasing more speakers from yourself. Many Thanks.
Mr Bate writes ;-the M3M Ribbons sound fantastic an absolute bargain.
Mr C Booen writes re the M3M Ribbons, Speakers are finished and sound amazing even with my old amplifier.
Mr Walker writes; I recently purchased 2 AVC1s from you and I would like to say I very much enjoyed building them, and the listening experience compared to my B&W VM1 is light years ahead.
Mr Gray writes;- regarding M3m centre, M3ms as rear, and M3tls as fronts, with SW4 sub, System now up and running,-Very pleasantly surprised by the sound, I especially like the sound of the M3tlms;- very clean and plenty of range.
Andrew and Ana from Gener8 Sound Solutions Ltd write(M3tlms); We have built and veneered the M3tlms in oak and they are looking and sounding great. We have set them up in our main system in place of our Quad ESLs and are using them daily, Our initial impressions are;..........Powerful controlled sound that instantly gets your attention,...Very impressive integration of the drivers (almost completely seamless),...Very musically engaging performance with excellent bass depth,........Excellent depth of soundstage, instruments well placed and voices located dead centre,.....Easily placed with a small footprint, making them very room friendly,.......Great to look at!. Ana and I would like to congratulate you on a superb product, that on initial listening confidently outperforms any sub £1000 speakers we have heard.
Mr A Seaford Lancs., ( Speaker designer) writes on the 5" Magnesium unit used in the M1tl ,M3tlm, M3m, AVC3, M4, S5tl, and M3m Centre. This is a remarkably good driver. It produces sound that is so natural and smooth just like real sound. When listening to the DAB radio on TV or from CD or DVD, the driver seems to give you all the source information in a very natural way without ever drawing attention to itself. I don't know of any other driver at any price that can do this. The frequency response is very smooth with none of the "nasties" that metal cones often display. This makes it easy to produce a crossover to give a flat response and integrate well with the tweeter. The designers and engineers that produce this driver should be commended for their considerable achievement
Mr C Hayward (formerly with Kelvin Labs) writes regarding the M3tlms; I have been an enthusiast for more than 35 years and was involved with the Hi-Fi business professionally for several years, owning many speakers, and using many more from floor-standers to bookshelf models, and I can honestly say that these are the finest speakers I have ever owned, and one of the best I have ever heard. In particular, the sheer transparency and believability of the stereo image produced is remarkable. There is no obvious distortion, colouration or over emphasis throughout the frequency range .The bass is well controlled in my 12ft by 15ft sitting room ,the midrange is clear with great vocal reproduction and the treble is faultless and detailed. My only comment regarding their suitability would be they are so neutral and revealing that they demand to be used with the best (not necessary the most expensive) source equipment and amplifiers. (Equipment used; Yamaha DSP-AX757SE and Pioneer DV-525 bi-wired SC2 (URM67) only mod lift speakers slightly higher off floor to suit the room)
Visitors from fellow enthusiasts to complete non-enthusiasts have been amazed that suddenly there is someone in the room singing and playing to them .One enthusiast commented that this was exactly what he is trying to achieve. The speakers were not hard to build (and I am not a DIY expert by any means) They have proved to be superb value for money.
Mr F Benson writes regarding M3tlm Ribbons; In March this year I purchased a pair of M3tlm Ribbons in total kit form, following a visit to you. Even whilst I was running them in and making adjustments to the wadding and crossover it was apparent that I had bought something rather special. I have now reached, if not the optimum performance, a set-up that far exceeds my expectations and is well suited to my listening room Together with the Williams hart monoblocks. I am absolutely delighted with them. I now have a truly spectacular system. A friend in North Perrot was so impressed he has bought a pair of his own. (and the monoblocks).
M3tl Internet review "ourworld.compuserve.com/homepages/cmelhuish/speakers. tm" How Do They Sound? Well, simply superb (to my ears at least). They are smooth with no harshness in the high frequencies, and of course being a transmission line design, the bass response is extended and "tight". Bass notes exhibit a degree of bite and detail not previously heard in my old bookshelf speakers, but none of the "boomyness" that is associated with Infinite baffle designs
Mr. A J Milverton writes; I Purchased the M3tls at the beginning of the year they are now complete and run in providing a distinct improvement over my previous speakers. They are well worth the time and money spent in constructing them.
Mr. Duberley, Greenford writes; A few years ago I purchased the M3tl kit which has given me hours of listening pleasure. The sound is so natural in comparison with speakers costing several times more.
Mr K Whitlock, Kent writes, I recently built a pair of your M3tls for a friend ,they are now run in and sound superb, as good as any commercial product at around £1 - 1.5k
John Gardener writes regarding M3tls, Just thought you might be interested to know that I finished the speakers about a month ago and that I am absolutely delighted with them, They really do sound far more expensive than they are and do have a genuinely extended bass response, my brother in law who is a real Hi Fi buff was go-smacked by the sound especially the bass when I played some of the Miles Davies "Kind Of Blue" Album. He thought they were worth well over £1000.
Mr S Crick writes, I finished my M3tlms last night and fired them up. I was very impressed by the scale and delicacy of the sound produced- and that was the first hour of listening. I understand they get even better when they are run in. Well recorded classical music was gorgeous with individual section being clearly heard. Many thanks for providing such a wonderful kit and for answering all my questions , I will recommend you to whoever will listen!
Eivind Fredheim Norway writes,; I bought a S4tl kit from you last year, but did not have time to build them. Started on them again a few days ago and now they are finished. I can not believe how good they sound!. Of course they need hours of playing before they sound their best, but they are already surpassing my expectations!! Will recommend them to everyone who has the room for them.
David writes (speakers built for him by Paul Clark Marlow) re S4tls; The speakers now are quite literally light years ahead of what we heard from --- speakers, I have never, anywhere, at any price, heard sound of this quality, now they are just sending little shivers with each new disc. just listened to Tom Waits, voice was just so amazing, listened to Floyd and scale of image just blew me away, I am now addicted to a Weather Report again because the huge scale of sound, musically and sheer rhythmic coherence- just makes it an absolute blast. I am holding back on the ultimate of Massive Attack.
Mr S Nicklin writes re S4tl Kevlar ribbons, Just to let you know I ,have finished the initial part of building these speakers and tried them out for the first time today. Even new and cold these sound special, The resolution from the tweeter is amazing- pretty close to the Martin Logan Electrostatic I heard a week ago (without the negatives which meant I couldn`t live with those) Range is superb and musical to a low frequency. I can tell these are special- within minutes, I am not critically listening any more just enjoying the music.
Mr P Korab writes; Id like to order some cable for my S4tl Kevlar Ribbons which are sublime, The speakers sound superb with an incredible amount of detail, I am hearing things that were only confined to decent headphones- and on basic 79 strand - amazing! I have not heard speakers that will live with these at any price and I've heard speakers costing up to 20k purporting to be "Hi-fi", even my partner was extremely impressed and she is not a Hi-fi buff!
Mr H Mourisdsen Denmark writes regarding S4TL Kevlar Ribbons, I just wanted to express my happiness with my new speakers. The soundstage is just amazing -its so well balanced and natural sounding, I have added 18gms of Wool to each speaker and it seams to work very well after 2 weeks of play.
Mr D Whiteside Chippenham, writes regarding S4tl Kevlars; Id like to add how pleased I have been with the S4tls which have provided sound quality, clarity, and dynamic reproduction far better than I could have hoped for the price. Also many thanks for your advice in selecting this model which I can now understand why it is the best choice for my living room.
Mr N Norris writes ; Just wanted to say thank you for designing such a wonderful speaker. I have just built your S4tls and they sound amazing! - The bass weight, clarity and scale far exceeded my expectations.
Mr. J R Stowmaket writes (letter to Hi Fi World regarding S4tls) I haven't done any woodwork since my schooldays, yet still managed passable results. I wouldn't have cared if they sounded terrible, but to my unbiased ear they are superb more than repaying the effort that went into them.
Mr. Hewett, Ponteland writes; At last I have found time to thank you for the fine pair of S4tls that are now working well in my living room . They have been running for over a month now and sound superb without any further tweaking . The Audio dealer who supplied my amp was amazed at the sound especially when I told him they were home-made and cost less than £300.
Mr. Morin Dunkinfield writes; I must say how chuffed I am with the excellent S4tl speaker kit I have recently assembled,. The sound quality is absolutely delightful , sweetly detailed , and has easily surpassed my expectations.
Mr M Blocki writes;- Just to let you know I have eventually finished building the S4tl Kevlar Ribbon speakers I purchased back in August, It has taken me a long time, 1 hour every the evening if I got the chance. Anyway it has been well worth the wait, they sound excellent, better than anything I have heard. The treble is smooth and very detailed and the bass is fantastic and well extended, even though they are probably not in the best positions.
Mr A J Law Preston writes; I purchased the S4tls from you some months ago and I would like to thank you for a superb sounding kit that is almost unbelievably good value for money. Before I bought the kit I had auditioned speakers up to £3000 in my room and the S4tls are light years ahead Thanks!
Mr. Ellis Cardiff writes, I am writing to tell you how pleased I am with The M4s I bought recently . I had expected them to be good but I was delighted with their performance .I really did not expect a box so small to deliver so much!
Mr S Crampton writes regarding M2 Ribbons, I finally fired up the speakers, having recently spent some time on the cabinet finishing and building the crossovers into the plinths below the speakers ,I was apprehensive about how they would sound. You may remember I am a Quad 63 owner, so I expect a lot from my speakers. No commercial speaker costing less than £1000 has ever caused me to sit down and really listen to music. These have. The midrange and treble is particularly outstanding- human voices are so accurate.
Mr A Jellett writes, My M5M kit is finished and nicely running in. Excellent! My Acoustics Engineering graduate son is very impressed with them. They look very good too with oak veneer and the grille fitted (small grand-children would be far too tempted by those lovely gold drivers if left exposed). Hard to describe but silkily musical without any loss of detail, especially on classical stuff. The Tag Test Tracks CD is brilliant through them. Very clear imaging as well from positions right across the room.
Mr B Cheal writes regarding 2 S5tl Waveguide Kits purchased 2012, First kit now completed- the speakers are up and running and sound lovely!
Mr J Farrell writes regarding the S5TL Ribbons; John from Glasgow here. Just a wee email to say a big thank you! I have put in over 40 hours in the last 10 days, since receiving my S5 Ribbon kit, and I fired them up for the first time just after 10pm with some Niel Diamond for a test. Wow! Ive just sold my ----Q900s I bought 12 months ago at a loss of £500 in 12 short months. Well worth it. I know I need to bed the S5s in, and the sound will change in that period, but again -Wow !. They sound so natural, with bass, mid, and treble all floating over a sound stage like I have never been wealthy enough to experience. A very proud IPL customer.
Mr P Carter writes regarding S5tl Kevlar Ribbons; Hello Ivan I have now had the S5tls running for a week or so. These things are incredible, so clean and deep. No tuning done yet as will run them in thoroughly first before I decide if it is necessary. Despite very heavy use they still appear to be changing as they run in. I have a pair of B&W Nautilus to compare these to (cost over £8000) and these are very much better. In fact we are having so much fun listening, my wife will not let me strip them down to finish the cabinets, but as soon as she does I will send some pictures of the finished articles , they deserve a world class finish. They go to very loud levels with my 38 watt valve amplifier and I dread to think how loud they will go with 200 watts. I may find out since I have a Musical Fidelity A370 power amp in the dining room system which will exercise them well. Thanks again for some wonderful speakers. These deserve a much bigger audience.
Ben Gaffer , Mombasa writes regarding S5tl Kevlar Ribbons, Finally got them built from Mvuli hardwood with a matching amp rack/bookcase, look wonderful, paired with a Musical Fidelity XA200R and bi-wired with good cable. With a decent recording they sound incredible and fill the house with sound! even with the tiled floor the bass is warm and deep and the detail from the higher frequencies is really staggering. What really astounds us is that they keep the detail even at higher volumes. Everyone is amazed by them... I am in the process of listening to all my music collection again! Best sounding Hi-fi in Mombassa for sure! Thank you for all the help with these!
Mr R Colman S5TLs in Thailand- last year (2011) you supplied me with the S5tl kit which I took home to Thailand. Finally I got them finished and I just wanted to say I'm absolutely delighted. They sound fantastic and wow everyone who hears them. A couple of photos attached. In the end the furniture company that made them veneered them in mahogany. The stereo imaging is a revelation, the impression of control is total, and in particular, voice and acoustic guitar is stunning. So many thanks for enabling me to build a truly great pair of speakers.
Mr. A. C. S. Lancs writes; IPL Acoustics really have an excellent range of Transmission Line kits. The sound quality of each design is superb. So far I have constructed the S3, S4 and S5tl kits. The S5tls are the finest speakers I have, and the ones I use for my daily listening. There are benefits from Bi- wiring and especially from bi-amping (which I use) The sound is natural, unforced and effortless , and the closest to the real sound I have achieved.
Mr A Marsden writes regarding S5tl Kevlar ribbons; Just finished putting speakers together- thought I would test them prior to attempting to Veneer. Initial impression is -Wow! The bass is deep, deep, midrange is clear and smooth, and treble is crisp and sweet- and this is without running in.... Sensitivity appears slightly below my Rogers LS7 but I guess the drive units should loosen up somewhat. Currently feeding them with PPKT-88 valve amp, with special Amorphous OPTs- marvellous stuff. All credit to you for an exemplary design- congratulations. Veneering will have to wait -time to listen to the CD collection again!
Paul writes regarding S5tl Kevlar Ribbons; The speakers have been completed for a while and look superb in their veneer, When I first connected them I was shocked how bright they sounded after my IMFs but as you warned me via your instructions it would take a few hours to run them in and of course I still had the option of "tweaking" the crossover or adding more Long haired wool. I need not have worried, after about 10 hours or so they settled down and wow! After 20 hours Yes! No tweaking required. To be honest I was so excited at completing them, I didn't even pay much attention to positioning, but they still sound absolutely amazing. A beautiful crystal clear top end, with a massive and controlled midrange, and that superb bass that only a transmission line can produce. These are mind blowing speakers, that bring a smile from ear to ear every time I listen. At first glance, hard to justify nearly £800 (complete with veneers etc) for "do-it-yourself" speakers, but I would say to anyone that wants to listen, go for it. I doubt you would get any change from about 5 times that amount, for factory manufactured units and very possibly they would not be built with the same care as when you do it yourself. Thank you so much for providing us all with affordable high end speakers.
Mr M Dryden writes;- I am mailing you to let you know of my experiences with the S5tl Kevlar Ribbons. I built them and ran them for about a week before veneering them and have to say they sound amazing, and look like they sound; Serious. They are being bi-amped with matching120wpc Nad Power Amps and sound extremely natural and open .I must say I agree with other reviewers in that I am hearing new parts in the mix of familiar material to me. In fact I believe the S5tls have taken me considerably closer to what the musicians and engineers must have heard in the studio, they are that good. Instruments sound very real; I play Fender Bass so know the sound well, and can tell when such an instrument is playing on a track, instead of a vague bassy boom that could be anything. Thank you for your advice, and all your research and development of these amazing speakers, I am delighted.
Mr G Gardner writes regarding S5tl Kevlars, After spending a great deal of time building and finishing the cabs the S5tls were tried out today for the first time with the Glow-Master using the Vandamme cable (bi-wired). My first impressions are that they to me at least are easily as good as the B&W 805s (£10k) if not better.. The bass is firm and expansive- without being overblown. (The Glow-Master controls them tightly). Midrange as ever is superb, and the ribbon tweeter produces effortless high notes, for me the complete package and for me the ultimate amp/speaker combination.. Female voices are projected with unbelievable clarity and naturalness. As they bed down- I expect them to improve further- but my expectations have already been more than met, and almost certainly exceeded. Another stunning speaker- in my opinion virtually without competition in the 5k-10k price bracket. I hope to compare them to the Revolver Cygnis soon- but I think I know which pair I will put my money on!
Mr I King writes regarding S5tl Kevlar Ribbons; I would like to thank you for all the help you have given in construction of the above speakers. Not only are they a fantastic pair of speakers, the quality of your after service is second to none. I appreciate all the help you have given me whilst constructing these speakers.
Mr R Youens Grantham Writes; The superb S5tl speakers I have just completed are indeed something out of the ordinary. .The level of transparency, imaging, and depth is quite extraordinary. The flexibility and simplicity of tuning the frequency response and damping for any particular room condition is a breath of fresh air for any enthusiast of pure sound. Being a Video Installation engineer by trade, I get the opportunity to see many audio set-ups on my travels and this speaker is in my opinion, up there with the very best and very expensive. After the SW2 and now the S5tls I am now saving for one of your centre speakers. I could recommend your kits to anyone who likes to get "hands on" and craves an absolute bargain
Mr P Carter writes; I have now managed to prise the S5tl speakers away from the wife long enough to get the furniture finish on them, They now look as good as they sound, and in fact are still improving. We have had some extremely expensive speakers through here recently and the S5tls are going nowhere. Some speakers seem to do a bit of the audio range as well and the odd one may be slightly better at a certain thing. than the S5tl, but nothing seems to give the completeness of the S5tl. I am now running them with Krell KSA 80 amplification and Townsend Rock 7/ Origin Live. Encounter/Soundsmith The Voice and they are stunningly good. People who hear them are amazed by their authority, yet delicacy. They are also accurate enough to reveal the slightest change to the system. If you have never heard the lowest octaves with these and a Townsend Rock then you are missing out on life.
Mr. R.W.P. Hampton writes; I am pleased to tell you the S5tls sound splendid .
Mr S Cobham writes, regarding S5tls; Thanks for great sounding speakers
Mr. J.R.W Scunthorpe writes regarding the S5tls; The sound is enormous ,detailed, having bottomless bass, without boom ( not like some commercial designs) . It is not really noticeable until program material such as Rhythm of the Saints is played and the bottom notes on the fretless bass really come out- I have never heard them before!. These speakers make my friends L........ s sound like surround sound monitors!.
Mr. Sinclair, Neath writes; Thank you for sending me details of your new S5tl Gold . this speaker looks like being another success for IPL following in the steps of its predecessor The S5tl which in my opinion was the finest speaker at any price anyway. Many of my visitors have commented and complimented on the sound quality of the S5tl and are amazed at the professional finish achieved from a self-assembly kit. One person refused to believe I had built them myself , preferring to think that I had gone daft and spent a small fortune.
Mr D Woodnott writes regarding SM1s: Speakers sound really good, I have made the cabinets from ply. At present cabinets are only screwed together, so will expect even better results once glued up and finished. Thanks again for a really good product
Mr S.J.March writes regarding the SM2s; Well I finally finished my SM2 Ribbon speakers today- AMAZING! So impressed with the sound already- thank you so much real treat for my jaded ears!
Mr R Innes Rotherham writes; I have been building IPL kits for more than 12 years now and have built most of the range for myself and other people and have become most adept at building the cabinets. In all this time I have never had a pair that does not sound superb. I have compared these speakers to commercial speakers at several times the price and have never found them to have been beaten. I can recommend these speakers to anybody who wants a high end sound at a very sensible price.
