I discovered something very interesting today.....the lower I can get Audyssey to set my sub level, the more headroom I have.
I was getting it close to -6db with Audyssey so I could boost it by 6db ending up at 0db and I was getting a little distortion at "0" MV. Completely by accident I had Audyssey set the subs to -9db and (after my standard 6db boost) the distortion at "0" MV disappearred....hmmm, I said.
So, I turned the subs' gain up a bit more and got Audyssey to calibrate them at -11.5db. I was then able to boost the subs by 9db with no distortion at reference! I don't plan on keeping it there since I'm kinda scared I may damage my house.
Anyone else experience this phenomena? I'm guessing having the gain on the subs as high as possible somehow allows for more headroom, but I'm not sure.
