Back-of-couch Bass Tap

In considering various ways to help out my odd room, it occurred to me that one way to treat the wall behind the couch would be to build a bass trap the size of the back of the couch, adding insulating material and or a membrane, and possibly hanging it from small hooks.

I mention this because I have a window behind one side of the couch, and I kept thinking about ways to treat the area—under and beside the window, etc.

Seems like this could work. I'm kind of looking for formulas for depth, type of material, type of membrane, etc. Also, any links to others who have done this sort of thing.

 

That will work. Dont cover the back of the trap. A frame is fine. Why stop at one? Make a few. More the better. If you make them thick enough, say 7 0r 8 inchs you should use the pink fluffy stuff, which means it will be cheaper and better performing. Dont forget the back corners, whats going on there? Where two corners meet will give you maximum absorbtion.

 

The corners are difficult to describe, in that the amount of flat wall surface is minimal. I am forced to consider hanging 6" traps from the ceiling in these areas, as the windows almost meeting in one corner and the other corner being more part of a longer wall with a small 10" wall intruding into the room where the ceiling changes height, present certain challenges.

 

Anything you can do will help. Just dont ignore it. 6db for free where to corners meet.

It was the best thing I ever did as it transformed the sound beyond measure

 

I have real traps behind my couch in my home theater room.

Use Roxul "Safe and Sound" insulation. Best stuff out there.

 

I have a GIK soffit bass trap behind our large sofa. It has a subtle but worthwhile effect, tempered by frequent threats of divorce....
