So I've been messing with my acoustic panels for a while, as well as speaker location. I've got a box of a room, around 12'W x 15'L x 8'H. I've got panels all over the place, specifically:
- 4 - 2" 2x4 panels on each side wall
- 2 - 4" 2x4 corner traps in the back
- 2 - 4" 2x4 panels on the back wall
- 4" panels on each front wall corner (outside the screen)
- 2" panels below the screen
- 1 - 2" 2x4 panel on the ceiling (for center channel)
I just moved my sub to the front stage, which significantly improved my sub response, but I'm still getting some weird nulls around 200Hz. Here are my response diagrams (red = natural, blue dotted = target, green = RoomEQ applied):
Any ideas on what I can do to improve this? The room is super-insulated, and ambient noise is <20db (mostly the projector fan).
I was thinking:
- Cut a bunch of small triangles to fill in behind the back-wall corner traps (since they are only 4" deep, there's about an 11" triangle behind them)
- Take my screen down, and put 2" panels behind it.
- Redo the screen wall side panels more like corner traps (although there isn't much space, so I'm not sure that would actually change much). I guess I could make them 8" deep instead of 4" deep panels?
Are any of these going to do much to help? Any other ideas?
Thanks!
