Thanks Sonnie! Those extra 'M's are very important, I think. Every design decision I made on these speakers was intended to reduce distortion effects, from the driver array to the cabinet shape to the complexity and componentry of the crossover and the construction of the cabinet. I think they sound remarkably clean and pure, even at high volume levels. In fact, a friend recently remarked after an extended listening session at high volume levels that he was amazed that he noticed no ringing in his ears. I believe that's due to the low distortion sound being easier on the ears. At least that's my theory...
Those extra 'M's definitely make a difference in that respect, having a load sharing effect so each driver remains within its "comfort zone", no compressing or distorting. On the larger models there will be more 'M's, allowing even higher volume levels with same low distortion characteristics. I'm currently in the process of putting together a pair of 8 midwoofer ML speakers (the 660s). I'll be sure and post pics of them when I've got them built.
