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.

what is above the ceiling, floor joists? And are they running perpendicular to the speakers if so I appreciate your finding. In my room the orientation of the floor joists seems to have made a major difference in the speaker placement.

enjoy the music

I am not quite as surprised by the results although in the perfect model doubling the measurement on the rectangle would cause problems. However what we don't know is the materials in the room,whether your measuring a blank room, ect. The one question concerning what's above the ceiling is the right one. Acoustical applications can make all the difference in the world. In my app. I paid a lot of attention to what went behind the wall,ceiling,and floor. Despite things I couldn't change about an existing configuration the result with regard to resonance and other issues was very satisfying.

Interesting take about the joist orientation, Sayas - I've never considered this before, but it certainly sounds reasonable (if maybe not as significant as some other more obvious factors).

Rives, I just went to the website, and found it to be most helpful. I wish I could have programed in the location of my stand and record racks. I moved the speakers around and the listening chair on the program. The funny thing was, I was somewhat close to where I should be. A little tweeking of lacations is required.
How do I find out about your room treatments? I'm interested in getting things into a better working order.
Gotta go and move my speakers!
