I doubt if there is something wrong with the PowerPlanes since they should not have any built-in filter to roll off the low-end response. You could hook up the PowerPlanes as 2-channel full-range stereo in place of your L&R 1.6s (with no sub and no PX05 or pre-pro filtering) to confirm that the PowerPlanes can produce sound below 100 Hz if the signal hasn't been filtered before it reaches the speakers.
Doh, good point, I should have done that (just run a signal with nothing up stream through the surrounds) while the calibrator was here!
I like the PX05 for when I bypass the pre pro, with an analog setup connected to the amp.
But I am also using bass mgmt in the pre pro when listening to digital surround sources. I didnt realize that was verboten. I never seemed to have a problem with it when I was using the 1.6's for surrounds.
But of course I have not had the px05 re-configured for the power planes as surrounds.... But I figured using bass management might make that unnecessary since I'm never sending a full range signal to them.
At the very least I should pull the px05 out of the chain for the surrounds I guess.
