HELP with Room Treatment See Slideshow

Interesting. Thanks.

The bass traps will be helpful. The asymmetry of your room is problematic, you are getting more boundary reinforcement from your right speaker vs. the left. Some kind of absorption on the right wall would be nice, except your equipment rack is there. I would consider moving the equipment rack to behind the speakers and treating right wall with some absorption. Still, with the juttting wall right next to the speaker this may not make much difference unless you placed the speaker more out into the room (away from front wall). Have you thought about different positioning of the speakers, something more symmetrical.

Synergistic cable has just come out with some interesting new free standing room treatments, pricey, but they look good to me. Don't know about their capabilities.

I really dont have much option but to leave the rack where it is. I understand the room has its limitations so I am trying to make the best of a challeging situation.

The one thing you don't mention is what issues you are having. Are you getting return echo from the hallway-kitchen side? That gives you a big unbalance on the left side. I would say try adding treatmenst to those areas to absorb any sound from coming back at you from that side.
Maybe reduce the reflectivity from the rh wall.
Hard space to work with. experiment experiment experiment!

Go to Fabricmate.com and check out the modular panel systems in their store. I (and my wife) think those look much cleaner than any of the clunky panels with feet you move around the room. They can custom fabricate any size and configuration, with any available acoustic fabric, you desire. Maybe the customized options a source like this offers will help overcome the aversion to wall mount solutions. The custom fabricated panel system that looks like wainscoting is easy on the eyes. Good luck.
