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?

I bought several from   www.readyacoustics.com. years ago.
In my small room, I now use only two (doubled @ 4" thick that I modified with several holes @different sizes) directly behind my speakers with the tweeter in aligned at the center of the panels.

It's easy to overdamp with these.

I believe Ready Acoustics will sell you coverings?

@mitch2  — thanks for those tips. I probably will want to use these for something more than room pads, because like many, I'm not so handy that I will be able to finish these into something long-term good looking.

@tvad  Good suggestion. I hadn't thought of subtracting and then adding back in. That would create a mix of diffusion and absorption I don't have there now.

@riley804 I have read about isolation a lot, but, first, my stuff was on a really solid and low coffee table and then I moved it off to the side. I figured I would sort out the room before the isolation. The speaker stands are new and very solid. Perhaps you'd do isolation first?

@slaw  Thanks for the reference. I'll check into coverings. I really need to see if my 20hz - 300hz range is dialed in before doing too much more with the upper frequencies (using my OC 703); so that's why I call what I'm doing now just "playing."

I’m not sure what the intention of the Corning 703 is for you, but I would spend a lot of time on the Acoustic Fields channel on YouTube.

This might take more effort but if you ceiling is low, it may be tempting to suspend several panels off reflection points on your ceiling.  I would suggest hanging them 4-6" off the ceiling.  Any panel will work more efficiently if you allow space behind it.

I use 2" foam spacers behind my panels
