@rlross3 If you want to bring out the big guns to tackle this problem. I recommend a DSP genius, Mitch Barnett. That is if you are a ROON or JRiver user.
Accurate Sound Reproduction Using DSP , Barnett, Mitch - Amazon.com
His company is Accurate Sound Home - Accurate Sound
You will have to measure your room with a decent mic ($100) and the free REW software. He will give easy instructions on how to do this. The dude is a genius on this stuff and can make your gear work.
I used his remote services for my small room. However, after a lot of testing with treatments and moving furniture, I was able to get great sound without the DSP. Not everyone has the ability to add treatments and move furniture, so the DSP is a great safety net.
There are other ways to do this type of DSP (such as in audio hardware) but nothing as powerful as what Mitch does his very expensive DSP computer software (I forgot which 2 he uses).
