I bought some Owens Corning 703. Now what?


I'm investigating the acoustics of my room. I have been doing REW scans and analyzing them with the help of a member here. I've played with sub and speaker positioning and settings to see how this affects measurement and what it sounds like. I've reached out to GIK Acoustics to get their advice.

But, because I wanted to just try some experiments before (possibly) spending a lot with GIK and/or other companies, I bought 6 OC 703 panels (2" x 24" x 48") to try, temporarily around my room, singly or in combination. I might even make my own panels if that seems worthwhile.

My question is: What are some useful experiments to do with the panels and where in the measurements might I see some changes?

Again, this is not to replace getting expert help; this is a way for me to start to learn by interactive experience how my room is affecting the sound. So, good things to try?

Unfortunately, the only OC dealer in my area who was sells the 703 panels does so by the square ft., not by the carton. He quoted me $2.86/sq.ft., six of the 2’ x 4’ panels (48 sq.ft.) then coming in at $137.28!
I went with the 6pc carton from Buy Insulation Products.com. Bought a 2’ x 4’ piece of birch ply, cut it into four equal pieces 6" wide, and made a 4’ x 4’ x 6" frame. The six 2’ x 4’ x 2" OC703 panels perfectly fill the frame: two side-by-side, three deep. Wrapped the frame with grill cloth, set the frame on a pair of 3’ tall ASC tube traps against the wall behind my listening chair.
That sounds great! Please let us know how things change with the new construction! I created 4 units with mine -- two were single panel sized and two were double panel sized and that gave me flexibility to move them to different places around the room, including the ceiling.
