[QUOTE="Kyle_Keating, post: 5328707, member: 582385"] I would aruge MMAG does... MMAG is hard to compare with, but if we think of it just like a dual gap design, two gaps and a coil that splits them both, you still have the same problems as XBL^2... loosing 50% of the active coupling. Its not the notch in the gap that reduces efficiceny in XLB^2, its the fact that the coil doest ever catch more than 50% of the total gaps... implying you have high flux density that remains uncoupled by a voice coil at all displacements. Neil, as you know, the same can be said about LMS, you have less L in the gap.... so there is a loss. In terms of MMAG, the orientation of the magnets should not matter that much unless its a more efficient way of getting flux from a magnet. Aura manged to do this at the expense of complexity with their radial design for example. I'm not sure MMAG carries the same value, it would take some careful analysis to determine how much more efficiency is gained from dividing up the magnet like that. [/QUOTE]
