Click here for price list
The M4 is a compact 5 litre Infinite Baffle monitor quality speaker using the superb IPL/5M/S shielded 5"bass unit with its steel 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 where required 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 (this presents a slight increase in cost over units purchased separately)
