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 don't see, with all of the advice given, where anyone has stressed the need to examine the corners.

millercarbon:
Also you might want to check out the Decware site where he has a very interesting analysis that explains why corner treatment as I have done is so effective.

Only the one comment and the two web page links. 
Probably everyone else missed it too.

Well, Foley says the corners aren't necessarily the spots to be in. He's done thousands of rooms and his data does not support that. He's mentioned it numerous times in his videos. Of course everyone can have their own opinion. 

I suggest watching a few of his videos. He does focus mostly on bass frequencies imo. Maybe because they're the hardest to fix.

Concentrate on below Schroeder frequency where the room is in control above it's the speaker that controls.

When I moved I to my current home 8 years ago I asked Dennis Foley about my proposed basement room, which has a low ceiling. He didn’t recommend it at all, and I took his advice and found a different room. 
I understand if there absolutely is no other alternative, but reacting emotionally to free advice from an expert doesn’t seem wise.

cissado, Miller -- I heard the advice about corners. I did a bunch of SPL measurements. In my room, corners don't have much bass; it's the front wall behind the speakers that's really overloaded.

Thanks djones. I'll look that Schroeder stuff over.

edunbar Oh, I'm not reacting emotionally. I understand his advice and others have told me, too. I cannot move the room for a few years because we have a family and will do a renovation at some point but I'm stuck where I am. There are many elements of this room that are pluses and it already sounds quite good. So, while I understand the kernel of the advice is sound, it was offered without knowing any of the details of my situation. My sense is that someone at that company (I don't know if it was Dennis who replied) figures they have all the business they can handle! That's fine. GIK and I are talking, and I want to see about Real Traps, too.
