The differences in each of these drivers is how they act above about 4kHz. Compression drivers begin to rolloff above that point, but at varying amounts depending on diaphragm material. The JBL 2410 rolls off steadily and is done by 10kHz. The Eminence MD2001 has a little more above 8kHz and the PSD2002 a little more than that. This has a great deal to do with how the driver will sound in a CD horn verses a horn with collapsing DI, and also with the kind of top octave compensation that is needed.
