@tommypenngotti  , reading this got me to thinking that my listening room might benefit from treating the left & right perimeters.  After you conducted the above experiment, what conclusions did you arrive at?

@immatthewj 

I just threw up a blanket over a beam that goes across my living room listening area and it blocked/absorbed a bunch of reflection...so I'm going with treating both sides , haven't decided on right side because it's a wall ...more likely to throw up some absorption panels there ....

Prepping a room is no small expense.  I haven't seen any spectral absorption curves on any of these sites.  That is what it's all about isn't it?  Curtains face a tough challenge for room effects midbass and below.  Solid panels need to be suspended from the wall about 4".  Manufacturers supply acoustic studies, but oddly this most important parameter has not been addressed.  No secrets or snake oil here.  Review Armstrong's products and Acoustimac Eco-core particularly before anyone else takes the plunge. 

The best room treatment, in my opinion, is to treat a room as a room that you live in.-Bookshelves, Art on the walls, Window treatments, etc..

In other words, lots of stuff. That creates multiple/random points for sound waves to disperse/absorb within a room.

You can get anal about making a room sonically 'flat', but that is usually the worst thing you can do.

Just put up a blanket where you think you need some absorbtion, and listen.

The time you take to learn how seemingly simple adjustments to your listening area, will help you learn what you like/dislike.

YMMV
