I originally posted here.. has the pictures and such and layout of my basement:
I figured I'd try posting here. In my on going battle I've made some major improvements with response for the LEFT seating position.. I can get it to sound pretty good.. The right chair however is sitting right in a null/mode/void of bass... Also if you walk around the room there are still a lot of voids/nulls here and there... I was wondering if anyone would have any pointers?? I'm thinking maybe the wall that separates the basement from the "finished" section to the unfinished section just isn't cutting it? Right now it is just Dry wall with some of the pink insulation behind it on studs..
In the newer layout I tried to make some bass traps in the corners (highlighted in blue). They are about 48 inches tall right now (about half way up the corner). The red circle is the wall with Pink insulation and drywall (the back of this wall is exposed yet, yes I can see insulation on the unfinished side).
Other things I've tried
1) added a smaller sub along the right hand side wall.. it is opposite of the 18" sub.. It didn't seem to clear up any nulls in the right chair position.. It seems like if I added 6 more subs I'd still have this wonkiness in the room.. I can't describe it but it just doesn't sound good except in a few areas..
2) I added 2'x4' traps.. these seemed to really help with just the highs and mids along both walls..
3) Anytime I move or add or take away subs to test I generally redo audyssey..
1) I've done some moves on the 2 15" LMS-R's in the front but doesn't seem to help.. plus the boxes are quite large and in the front is kind of the best place for placement.
2) probably going to add a couch soon down there as well.
Any ideas? Could my middle wall be the main problem?
