The Driverack platform doesn't have any idea if you are using powered or un-powered speakers and amps.. or does it make any difference...The PX offers all the crossovers, and filters.. you just don't have 6 outs (only 4) you can't sum anything, and the DRPA+ offers superior auto EQ algorithms, and mute buttons and real time RTA for only a few bucks more..

Technically, if the POWERED speaker isn't plugged in.. it's not powered either :roll:
