Even "room correction" software doesn't actually correct the room -- It finds problematic frequencies and eliminates them. It makes the room seem better by making the speakers less accurate.
So you might not hear that 10dB peak at 130Hz -- But you won't hear any 130Hz -- because it's gone.
And EQ'ing a room into 'accuracy' only works for for a single point in space. Theoretically, you could make EQ corrections to make a single point somewhat accurate. However, if that point in space happens to be precisely where your left ear is, it doesn't mean a thing for where your right ear is. On top of that, if you're in a 30dB null point, it's going to add 30dB of (pick a frequency - Perhaps somewhere between 70 and 100Hz) to the speakers to make up for the null at that particular point in space - Which (A) will probably blow the speakers and (B) wouldn't have a thing to do with a point in space less than a foot away (up, down, sideways, forward, backward -- All will change drastically within a foot).
The *only* effective way to correct the frequency response in a room is to correct the room.
