I've measured a few of Eminence's compression drivers made after the PSD2002. They are fine, but didn't push me towards offering them. You can try the ASD-1001B, but to do that you'll need to adjust the R1/R2 values to compensate for the reduced sensitivity of the ASD driver.
As for volume adjustments, that suggests making a change in the dimensions of the cabinet. That would require a whole new set of acoustic measurements to find out what the change has done to the internal standing waves and the resulting response curve.
