Okay I finally setup to calibrate my system with the Rat Shack SPL Meter and Avia. First thing I noticed was that the SL and SR channels seemed to be switched. The cables running to the speakers from the receiver were actually correct though. I switched them anyway and it solved the problem? I actually noticed this last week while watching Terminator. Very odd indeed. And of course I had issues with the sub setup. After balancing all my channels and throwing in Ep. 1, I ended up cranking the sub level from -20.0 to -13.0 or -12.0 on my receiver. I must say though having all the channels balanced did WONDERS for my system. It sounds seemless now. Why the hell I didn't do this 2 years ago is beyond me.
