Changed Speaker Placement NOW BOOMY

Hello,

I have a bit of a problem. We bought new furniture for the living room where the stereo is and after replacing a couch, adding a chair and moving the speakers and audio rack down about 2 feet towards the corner and the speakers which where about 3 feet off the wall before are now about 14" off the wall.

I now have this unnatural sub boom and since I am using thiel 1.6 which have very little if any sub freq I can only assume its the room.

I understand that moving stuff around can do this, but its such a big change and I really dont have much room to play with.

Are there any cheap cheap cheap ways of fixing boom bass in a room.

The room is 12' X 26' with 9' ceilings.

If you look at my system pix the stereo is sorta in the same place with minor adjustments.

Any help would be super awesome.

Kijanki, in wave length yes, but the corners are acting like a horn load and things around the corner can change or break the wavelength. We need to kill the frequencies from being radiated from the horn. Tim

By the way, I cannot imagine your chair being hard enough to reflect bass wave, but for now, just put a blanket over it and see what happens. Tim

Timlub - the nearest side wall is 6 feet away and yes they are towed in a tiny bit. As for the golden triangle rule, maybe a slight variation of it.

Thanks.

Timlub - Yes, corners are the worst (I have window in one).
Damping materials work effectively to about 100Hz at 2" thickness. Further down it requires going to 4" panels (dense fiberglass) and positioning them 1/4 wave from the wall. I'm in process in building 2" panels (dense fiberglass material) but have to take care of corners as well. A lot of work and it doesn't come cheap. In addition there is WAF.

Kijanki, are you willing to build your own traps?
Go to hardware store, buy 8 inch sewer pvc pipe, wrap that in unfaced fiberglass, cover it in cloth, attractive top and bottom cap (maybe a 2x12 cut and routed, painted or stained, it works great.
6 foot trap cost about $25.
