Room Treatment

Talk to the folks at GIK Acoustics. They'll advise over the phone. Their wall mounted 244 bass trap panels behind speakers and 242 panels on side walls and on wall behind listening position made a big difference in my room (similar dimensions as yours but more reflective, I'd say). Floor standing soffit bass traps in corners have much less of a noticeable effect though I continue to use them. 244 & 242 panels definitely some of the better money I've spent on audio, in my opinion.

Ghosthouse,

Thanks for the response. I talked to GIK a couple of days ago and they recommended soffit bass traps in the corners. I submit they recommend their most expensive products. I know the ASC 16" round tube traps I tried in the corners had very little effect and now I'm wondering what to do? You have the 244 panels directly behind your speakers?

That's a good sized room; have you tried clapping your hands in the center of the room to hear how "live" it sounds? Does the bass sound tight or is it boomy? You may find that you need some absorption or diffusion panels.

It's good that you've got the speakers away from the walls, but 2 vertical absorption panels behind the spkrs and 2 on side walls would benefit, just as Ghosthouse has suggested.

Yup, Ric...One 244 panel behind each speaker. You can always do just a couple things at a time. I thought those 2 bass trap panels alone gave a big chunk of the improvement I got.

By they way, that's a beautiful finish on your speakers.

Did you rotate the ASC 16" bass traps? ASC designs them so half is reflective and the other half absorbent. A friend of mine uses them and spins them according to the music he is listening to because they have a huge effect on the sound stage.
