I have dual 15" sub's in my home theater and thought they sounded a little over the top on heavy bass scenes. I checked where Audyssey set them last and the value was -1.5. That's well within acceptable range.
I then turned the subs' gains down a notch and ran Audyssey again and this time I got -12. mind you, I turned them down and not up. I had to turn the sub's down to almost 0 to get a reading of -3 again when it had set the sub put to -1.5 at about 9 o'clock before.
Anyone have any ideas why this would happen? I moved nothing in the room but a couple pillows on a couch.
