I've finally started calibration of my system. I realize room acoustics play an integral part in calibration. But no matter what, I get a large peak at 90hz.

SVS PB10 sub.
AVR set 80hz xover, small.
No filtering, or processing going on.
Bass/Treble set to 0.

It just seems odd to me with the AVR set to 80hz and the brick wall the 200s have at 80hz that the system would peak at 90hz. This is pretty much the case no matter what phase setting I use on the sub.

Will the 200s perform to full potential using a 60 or 100hz xover?
Yes, I've inquired on another forum, but figured I'd come to the source regarding the 200s. Graphs using two different phase settings below.
