The IPL Acoustics M4 is a compact 5 litre Infinite Baffle monitor quality speaker using the superb IPL/5M shielded 5"bass unit with its cast chassis and light but rigid magnesium cone, and the excellent  Fountek CD 1.0 ribbon  tweeter with its ultra light 10mg ribbon and high strength  Neodymium magnets. This speaker gives a large scale  performance for its size with a good tight bass ,smooth, but detailed mid-band and a transparent  but delicate treble. This speaker can be freestanding or placed close to a rear wall or corner.   The M4s will compete with the very best of small speakers giving a smooth and very natural sound,. For best results use with an active subwoofer such as the SW4 or SW5.

The crossover is bi-wired and . It uses quality IPL polypropylene capacitors  and Super power inductors and resistors. The M4 may also be used in closed cabinets of between 4-8 litres , and ported cabinets of between 8-13 litres (see M3M Ribbon). The crossover is mounted on the rear of the CP4L Gold bi-wired connection panel supplied with the Plus kit.

The ribbon tweeters have been tested, and individually matched for use in the M4 kit. When i played this pair after building them I was stuned they are almost as good as the M1's and so much better than my old PMC DB1i's, so much. Now with magnetic grill covers for a cleaner look.

HiVi Research IPL/5/M with its magnesium cone and cast chassis are superb quality and represent the latest advances in driver technology.  IPL driver's has been genuinely researched to give smooth response and excellent sound quality at very competitive cost. These drivers are not a compromise, they are beautifully made and packaged and will compete with the best.












Fountek CD Neo 1Ribbon tweeter with metal face plate, aluminium ribbons, neodymium magnets results in superb sound reproduction. The advantage of the ribbon is that it has 10 times the force to mass ratio that a dome tweeter would have, and so is faster and more detailed. The Fountek are some of the best and most consistent Ribbon tweeters available, having a transparent but not harsh sound quality
