Ozzy, I also have the Auralex Roominator kit and a couple 3" burgandy panels that I purchased from Guitar Center a few years ago. I have had good results with this product, especially when I put the hand made corner traps in the rear corners and the diffusion array behind the listening sofa. I was having a bit of a upper bass boom which the Auralex took care of. It is an affordable tweak, couple hundred dollars, which is worth a try probably with a 30 day money back refund.
