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?

@jetjuice  Thank you for your replies. It's a privilege to have someone with your experience taking up my question. I'm trying to calculate the amount of reverb with REW.

And at this point, I'm playing with the material -- to see how it affects what I hear and what I measure.

FWIW, I don't expect to be able to become an expert by messing around with a few panels, but I expect to get some experiential insight into how the room can change. (Sort of like the way we try lamps in different parts of a room, with different bulbs, and then stand back and see how it looks, or sit down and try to read, etc.)

@vermonster -- Good suggestion. I'll try some doubled up layers, especially after I play some test tones to identify where the bass is really piling up in standing waves.

@mesch Thanks for the building material suggestions! I definitely need a project!

IMHO, the foundation for a great room begins with managing the bass as pointed out above,  the most difficult and the most expensive. Start here.

    I don't see, with all of the advice given, where anyone has stressed the need to examine the corners.  That is the first place that I would start with.  Others have already given good advice for ceiling and walls, but suggest that you ignore the guy who wanted you to wrap yourself in fiber glass.  Good luck.

You forgot to mention the importance of wearing safety goggles with your very informative instructions. The eyes are one of the first points of entry for that crap to enter!

@bigwave Thanks so much. Bass is primarily what I have been measuring in my room. Moving speakers, listening position, the sub, doing the sub crawl, etc. But this chart looks very handy and may have some ideas I've missed.

@assetmgrsc I've definitely been interested in corners and will give them a hard look. Yeah, and no fiberglass Santa suit for this grinch.
