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?

Hey @hilde45, good post ... the first report-post shows that you have identified two symptomatic areas in the mid to high frequency range.
As another experiment you could double-up panels (2 x thick etc. gives double the bandwidth, roughly) and extend absorption lower. 
The ceiling should be a deep panel (example 5 inch depth), with long narrow panels-spaced at different lengths apart to gain a baffle effect.
400 - 4000 wavelength range (3 feet - 3 inches) will likely need the most attention other than bass.
A Tube Trap(ASC) would go a long way to tame bass and help with mid to high frequency.
