LMT is actually more linear than XBL^2, but I haven't seen the methods used to achieve that, be it more inductance and so forth. Their prototype was fully linear to 45 mm (NOT a typo) of excursion one way, for a full 90 mm of linear excursion with NO drop in BL over the entire curve.

they wind the coil so it has ridges and valleys...

BL is rather simple to measure, and modify... you've got the flux, and the wire..

XBL^2 modifies the flux field in relation to the wire, LMT modifies the wire in relation to the flux field..

i cant find the post were dan commented on the LMT thing, but the conclusion was that in the end was that it needs a TON of power to get loud and certain pieces add cost to the driver and someone had a prototype and got the result that it needed to run with at LEAST 2000 rms or some crazy thing like that to get loud, damn i wish i could find it.
