You can spend big bucks and experience a lot of frustration trying to eliminate dimensionally induceds nodes and still not succeed. It has been my experience that the only nodes that are important are the ones at the listening position. These can be controlled to some degree by speaker placement and listening position placement. A good CD with pink noise tones and a RS meter and graph paper will be of great help to you. There has been a lot of discussion on this subject on this site and on audioasylum - you might like to do a search and see what you can draw from the prior posts. As i recall they contained some excellent explanations and suggestions.
Resonant modes and taming the room
I measured my listening room and calculated the room modes, and graphed them today. I was trying to determine if/where the resonant frequencies were too closely grouped. Ultimately I was pleasantly surprised by the fact that I do not show any serious problems.
My question though is, how can I tame the room to eliminate the areas of congestion in the modes I am experiencing? Are there differing approaches based on the frequency of the modes?
My room is L 22'-5" x W 12'-10" x H 6'-5". I was concerned about the low ceiling, but it appears to help in this application rather than hinder.
Any insight you might offer would be appreciated.
