Audyssey has always done a great job in my fully sound treated theater, but my 2.1 (in wall) living room system has always sounded bad. It's a horrible room for acoustics. Large, 10' ceilings, wood floors, open to many other rooms, very little absorption. The system always just sounded weak and non amplified. I'm using Polk V85's for the inwalls and an older 15" sub. The sub always sounds great, but the inwalls were just not impressive at all. For years I had an el cheapo receiver running it, but after a theater upgrade I moved the old Marantz SR7002 into the living room thinking it would increase the quality. Ran Audyssey for the first time and it really didnt change anything at all. The $200 receiver sounded just as good as the Marantz. I was sad.
Fast forward to last night and I had some time to kill so I started manually playing with the EQ on the Marantz since the old receiver didn't have the ability. I ended up increasing the lower frequencies by 4-5 db on the left and right. I did this by ear not with any measuring equipment, but I must say I really got it sounding great in there. The voices are finally deep and powerful and not tinnie and weak like theyve always been. Just wondering why. I mean, Audyssey was built for bad rooms, but it seems like it doesn't handle them that well.
