The problem that I see is that you are trying to apply a correction to a system at the wrong point in the reproduction chain.
If your listening environment is typical then there will be nulls at particular frequencies, and a peaks at frequencies, a correction system will adjust the gain of the these various frequencies to give a flat response at the measuring/listening position – all good. However, if you now move your listening position a few inches, the distances to walls, floor etc will change and a different set of frequencies will be at null along with other frequencies being boosted by the room. The correction system can't compensate for both cases.
The typical size of room peaks and nulls in an untreated room is in the order of tens of dBs, so your system could be being severely stressed in order to produce enough power in order to overcome the room's nulls. Meantime, at other points in the room, the same frequencies are now tens of dBs too loud, causing nuisance to people outside the listening area.
Not as sexy, but acoustically treat the room. I don't mean to cover the room in glassfibre, but a few scientifically placed pieces of room treatment can bring the room under control and let you hear the music, not the room. Additionally, you can have a wide listening area and not annoy the neighbours.
Here on audiocircle, there is a whole discussion area (Industry Circles => GIK Acoustics) that cover such treatment.
I hope this helps,
