Let's not write off mass completely. It is still relevant, but is "swamped" by the effects of the voice coil's inductance. And, in a very general sense, the difference in mass from one driver to the next of any given size is very small. Speed is a frequency response thing....isn't that right, Jean Baptiste Joseph Fourier?

edit: The huge advantage of XBL^2 is the shorter coil and lower static inductance. Oh, and linear BL can be achieved through manipulation of the flux field rather than through manipulation of the windings....that's a big difference, too, compared to LMS/LMT or Split Coil.
