From your room dimensions it appears as though you might have a standing wave problem. This occurs when 2 dimensions of the room are equally divisible (usually the parallel walls in-front and behind your speakers). Standing waves create bass 'hotspots' where bass frequencies are in phase, and pockets where bass frequencies are out of phase.
If your listening position seats you 'in' or at the high point of in-phase standing wave you hear double the volume of the effected frequency(ies). Conversely if you were to seat yourself at the low point where the standing wave is out of phase you would likely hear very little or nothing.
Your room isn't that large, so its my guess that you're getting a 'sympathetic resonance' from the drywall in your listening environment - a singular bloated bass region. And that THIS is probably a product of an in-phase standing wave.
What height is your ceiling in the room? ...If this too is divisible by the same common number you are unfortunately trying to make music the acoustic environment from hell.
If I'm correct the only practical thing (that I'm aware of - aside from digital room correction) is to calculate the standing wave frequencies, and see if you can eliminate them with bass tubes or other similar absorbers. Another (although less desirable IMHO) is to find the offending frequencies and modify your crossovers to compensate for your room issues. This could be done by the speaker mnfr.
Any one else have a different diagnosis/suggestions...?
Good luck with it,
Mike
