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?

@rc22 yes, your best bet is to call local commercial/industrial insulation companies and ask for semi-rigid fiberglass.
When I was building panels for my room, I had contacted GIK and they suggested I go with the Knauf Insulation. This is what they use in their panels as well and is brown in color. 2 feet by 4 feet. They have a DIY section on their website and you can buy it from there. 
I had trouble finding the 703.  Not carried by big-box stores, and I called all the HVAC installers in the area to no avail.

Ebay was the answer.
There is an online seller named Buy Insulation Products.com. They sell the 6 pack of 2" OC 703 for $105.50 with free shipping. Cheapest I've found.
That's about what I paid. I think the best deal I've found since then is to find a local insulation company that sells it and just go pick it up with my car. It comes in around $65 for 6 two-inch by 4 ft by 2 ft sheets.
