Echobusters "to gap from wall' or not

If you are going to go through the trouble of doing that, you might as well fill in the back gap that you would be creating with poly fiber-fill. The amount of low frequency extension that you would get by just spacing them off the wall would not be as drastic as increasing the thickness of said panels. Then again, if you are going to go through ANY added construction, why not just build them yourself and do a better job to begin with ?

I know it is easier to do what you want to do now because the majority of the project is already done, but for what you'll end up spending to buy these and transport them, you can build something better and more suited to your specific room dimensions. Once you start a project such as what is being discussed, you'll find that the motivation to do so was the hardest part of the equation. Room treatments are a BREEZE. That is, so long as one has the room and a small amount of tools to do so. Sean

Hello Sean

I've read Jon Risch's DIY 8" thick fiberglazz absorption panel instructions. I just am not one that is able to get burlap or whatever to behave that well. Plus it wouldn't really work with my room decor.

I didn't mean to try and discourage you from attempting what you wanted to do. I was trying to point out more cost effective and better performing options. I need to remember that some folks are "handier" than others though.

With that in mind, extending the Echobusters off the wall should lower their cut-off frequency a bit. Just keep in mind that exposed wood will also cause diffraction / reflections. Good luck and i hope that your efforts are well rewarded : ) Sean

I've done it. It makes a noticable difference in the effectiveness of the panels. I cut 1/2" x 1" standoffs and screwed them into all four corners of the panel in back. Then I bought a sheet of those small rubber peel-off circles for furniture and put one over the screw heads so it would not scratch the wall. Go for it.

I've also found that home-built panels just don't sound as good as Echobuster products, even if I try to get the same wood and foam. Something about that wool fabric maybe?

tell me more

I was thinking about putting circular styrofoam as the offsets blocks (predrilled)and then putting pillow stuffing or something behind it.

I didn't do the Risch thing because I am terrible at anchoring heavy stuff to the wall - any suggestions???

thanks
