Stacking 4' Panels in a 8' Tall Room?

[NewSc2]

I have 8 4' tall bass trap panels that I want to stack in the corners of my room (2 in each corner). It's a converted bedroom, so the ground is carpeted and the ceiling textured.

The problem is that two panels won't stack together to fit underneath the ceiling. I'm guessing the ceiling is about 2" too short for both to fit.

I was thinking to just hang the top panel as high as I could, and lean the bottom panel in front, but I just wanted to pose the question to see what other slutz have done...

Advice?

PS Happy New Year!

I would just put one in each corner and put the others straddling ceiling to wall corners. Like this

Hey Glenn, thanks for the reply. I am planning on purchasing more bass traps in the very near future, to fill in the ceiling-to-wall corners.

If you don't mind me asking:

Is the benefit of covering these ceiling-to-wall corners better than covering the tri-corners of my room?

How have you advised your customers to stack two panels in my situation? (or do you suggest that at all?)

I do like stacking floor to ceiling when you can, but in your case you just can't and doing it the way you want is not recommend. The 2 sides of the trap should be as close to the wall as possible. One thing you could do is push the ceiling to wall traps (like in the picture) all the way to the corner to cover the tri corner area. Either that or you could have the traps custom made to fit your corner.
I want to note that I am being kind of anal about this. If 2 fit with only a couple of inches off the side wall it still would work, but not as good. I am trying to give you the BEST solution vs a OK solution.

Just wanted to add a note. I adjusted the panels a bit and figured out the difference between the 2 stacked panels and my ceiling was less than 1". It was an extremely tight fit, but I got both to stack underneath.

So far it looks like from the pressure alone (and a very slight inward angle) the panels are holding up without any mounting. If the panels begin to compress at all, then I figure they'll be much easier to mount correctly.

I gotta say, I had 4 4" panels sitting around the ground in the corners, and had noticed a slight tightening of the bass. So far I've put 7 4" panels up, and used the 8th as a bass trap behind me (the last corner is kind of complicated, with a window and a closet). The bass has noticeably gotten tighter and bigger at the same time. The overall sound is a lot cleaner, with more soundspace.

I'm in the middle of putting 2" panels at the first reflections on the sides of the room, and diffusors throughout. Looking forward to new ears tonight =)

Good deal. Let use know if yo have any other questions we can help you with.

Hi Glenn! I actually do have a couple more questions. First off -- my room already sounds much improved, so I'm very pleased with the results already.

1. My last corner (specifically the back-left corner) is where a window meets a closet. I won't be able to "seal" the corner off floor to ceiling no matter how hard I try (due to the window pane depth and closet), and I do use the closet from time to time. Right now I have 1 bass trap freestanding in the corner, and I've used the other as a bass trap on the wall directly behind my listening position.

Should I still try to complete the 4th corner floor-to-ceiling, or can I still get decent results from putting 7 corners panels out of 8 up? Should I hang the panel up or leave it freestanding? It'll have to go high, like in the 3.5 to 7.5 feet range.

2. Because I had to angle the bottom bass trap in my other 3 corners to fit floor-to-ceiling, the lower bass trap ends up with about a 1-2" space near the ground between the trap and the wall. The top of the bottom bass trap and the full top bass trap is flush against the wall.

Would I be able to notice a difference if I try to have the panel flush with the wall the full way through? Should I stuff anything in there to seal this off?

Keep in mind that I will be adding more panels over the next few months for the wall to ceiling corners and a couple vertical panels on the front wall.

More is always better, but if it sounds good now then it can't be wrong

Freestanding is fine.

If the trap is that close then I dough you would hear a difference. Don't worry about stuffing anything in there.

The more corner you cover the better the response will become.
