Hey All, Contrary to the advice of many fellow forum members I've been runnig my SVS PC+ in conjunction with an older Sony 12" powered sub for a few months now. I am totally happy with the sound I'm getting with my system but the more I read on the forum the more I start to wonder about my two subs being out of phase. Both subs are in the front of a 10x16 room in their own corners. Since I've never previously messed with the phase settings I can't help but wonder if I'm missing out on any performance/output. I'm not sure what to listen for when adjusting the phase knob on the SVS. My question is; how do I properly calibrate phase settings, and can I use AVIA to do it? Thanks.
