STANDING TALL PERFORMING PROUDLY
M350, M340 & M250
350 340 250
The floor-standing model M350 and M340 speakers have no fewer than four woofers and a 4½-inch mass loaded mid-range driver. With so many drivers it can instantly flood the room with an ocean of audio sensation. And because we have used four smaller woofers rather than one or two larger woofers, the cabinet remains, slim and elegant. Ideal for the music lover who demands the ultimate in audio perfmance and is also looking for elegant perfection.
FLOOR-STANDING SPEAKERS M350, M340 & M250 Throughout the M-Series, only the best materials are used. Best in terms of acoustic performance and luxurious-feel. For example, their slim elegant design is finished with a choice of either high-gloss black piano lacquer or rich walnut veneer, each with a luxurious leather-feel trim. The result is a sense of exclusivity and style that seduces not only the ears, but also the eyes. A common problem with conventional floor-standing speakers is the build-up of standing waves and their consequent interference. No such risk with the M-Series. By using four smaller bass drivers in the M350 and M340 (rather than two larger ones) dual oscillation and standing wave creation is simply not possible..
