Room Acoustics: Where to place the squares?

For the OP and @4krowme I have some brands:

GIK Acoustics - Great performing, not the cheapest, but high value

ATS Acoustics - Even cheaper than GIK, also good but GIK has some models that are exceptional

amcoustics.com - Great resource for learning about room modes and room acoustics.

The bottom left of the Amcoustics page has a calculator for panels.

 Thanks Eric,

 Good choices you have there. I want to be interested in them, but it ain't gonna happen. My question was aimed more toward what info the OP has about what he has chosen to use. We know nothing and can assume little.

No more info than you're giving might as well place the squares in the closet. 

@magister and @erik_squires

That acoustics.com site talks about room modes.
Are you two fellows also discussing room modes?

And what is OP looking for? Room modes?

 For a while, I worked for the local college repairing some of their abused machinery. Usually the ticket would read "broke" or "doesn't work". What we have here is a lack of communication. One of my favorite movie lines.
