That corner is available, and we have not tried that spot with audyssey turned off, so when I get home I will move it there and do some listening.
In almost all spots in the room we have tried toggling the phase switch, and it has yielded no change in sound at all. The main speakers are BIC America FH-6T's, the center channel speaker being from the same series. And the surrounds are BIC PL-66's.
I do have an spl meter, and I have the hsu bass test cd. Would using the third octave warble tones on the cd be worth using with the spl meter? What is the process for using the meter to measure? Does the sub need to go in the listening position? More info on what to do with the spl meter would be great!
I will update you once I get a chance to move the sub!
