This story is crazy and long, so I'm going to summarize it. Seven years ago I was able to recover some Owens Corning 703 from four cubicle walls that were stashed in a basement at an old factory job. OC-703 is the bomb for broadband absorbers, as we all know, so you know I was thrilled when my boss said I could have them.

I ended up building wooden frames and stapling in fabric. I stayed late after work and built them there, probably 3 hours a day for 5 days. I didn't actually take any pictures during the build, which upsets me because now I'm ready to share the result.

The sad thing was, as soon as I built them, I ended up moving to an apartment and f or whatever reason, I never hung them. I moved again and finally did mount them and WOW! A world of difference.

Here's the pics. I'd like to point out how flush the fabric is across the face of the panels and how I mounted them with spacers. The reason I have smaller panels along with the larger reflection panels is that only two of the cubicle walls had full pieces of rigid fiberglass in them. The other two were comprised of smaller (but uniform) pieces.

Along this journey, I became very obsessed with acoustic treatment. I finally compiled all I know in one giant overview of the topic, which I think a lot of people could use as an introduction to the topic, found here: http://ledgernote.com/features/acoustic-treatment-guide-for-panels-and-foam/ The difference this made in the quality of listening and recording in my room is unbelievable. It's literally a world of difference. It blew my mind.

I can't even imagine what it's going to be like once I build some super chunks for the corners. I need bass trapping desperately, but just removing the crazy reflections and reverbs made an insane difference.

If you're considering building or buying acoustic treatment but are hesitating, don't! Seriously, DO IT! You're going to love it. It's CRAZY, and i'm mad at myself for waiting so long to mount them. Get it done and live the high quality life!
