I wouldn't put the wooden back on it so the sound can pass through and then reflect off the wall back through the bass trap for further absorption. Air gaps really boost the effectiveness of traps. Try with a fabric back.

I thought the same thing until I saw that it's basically a thin piece of card. Something like that would only reflect high frequencies and those aren't making it through the rockwool.

I agree.the backing is there for structural reasons. But it could be replaced with slats to provide triangulation. Also, it looks like insulation as well as the walls help keep it stable.

Follow up. I built these and they didn’t do all that much to tame 40-60hz. I built 2 diaphragmatic bass absorbers for 40hz and it was infinitely more effective. It took several hours to plan and build and they are extremely heavy but well worth the effort.

Hi thanks. I guess I just wanted to make sure the fabric didn't tear in the long run. It might work fine either way

I guess so, its just very convenient using this particular shelf since the width is the same as standard insulation sheets - no extra cutting needed.

@ProbablyStereoClub Жыл бұрын
You don't want the fibres to escape! Plus, a few millimetres of board wouldn't stop anything but the very highest frequencies - and those have already been absorbed by 3 layers of rockwool. Sound wise, it doesn't make a difference.

Thanks. Judging by other's accounts, a reasonably quality fabric should prevent fibers from escaping. You could always wrap the insulation in plastic, as extra precaution.

The plastic will have little to no effect sonically... in fact you could just use the material as is in the wrapper... not attractive but it would work.
