[QUOTE="Kyle_Keating, post: 7133715, member: 582385"] Fair enough, i think we made all of our points as well as we could. I'll respond your overhung depth challenge: I'm assuming you're using dual 4mm gaps in a 20mm tall xbll gap plate with 16mm tall magnet with a 16mm tall voice coil. How about a 32mm voice coil with a 32mm tall magnet with a single 4 mm gap. That gives me 14mm xmax and 18mm xmech at the same depth. One last thing about inductance over displacement - while i have not done AC analysis myself, i feel its less important because if the voice coil is moving quit a bit, the inductor portion of the motor is basically a short circuit no matter what the value is at that point because which is obviously why inductance is a low pass filter - it just doesn't matter too much down low because its a short circuit. By the time the inductance really kicks in, the displacements are very small. How much that matters without any math to back it up is debatable and i'm not gonna divulge in that conversion, but I do feel this last point needs to be made in light of all loudspeakers. [/QUOTE]
