yeah, i wasn't trying to give a full explanation of driver limits. just wanted to let him know that xmax doesn't mean the damage point. heck some drivers don't even make it to their spec'd xmax.
for an overhung driver, broadly speaking, the various methods give pretty similar results whether one uses the 10% thd point, -10%bl, (hc-hg)/2+1/4hg.
av, it is BL (B is the magnetic field, L is the length of the coil in the field).
