* The air motion transformer driver moves air like an accordion’s reed chambers. The result is an extraordinarily rapid response rate and very low distortion. See http://en.wikipedia.org/wiki/Air_Motion_Transformer.

** The copper shorting ring prevents the voice coil from moving out of the magnetic field resulting in tighter bass.
