This might seem like a dumb question, but ill ask it anyway. I have a pioneer reciever with Multi-Channel AcoustiC Calibration System (MCACC), basically have to place a microphone in my listening postion and the system plays tones a different levels and adjusts accordingly. With that said, Would I benefit from a Behringer Feedback Destroyer or did the Pioneer's Calibration system already smooth those LFE's out?
