Speaker corrections only works in rooms that are death acousticwise, or outdoors.
In "normal" rooms you ever also correct your room response. And at the point you have to measure for the coneq your room will sound completly different from the sound at the listening position... So in reality you correct a point in your room where you never listen at.
This is mostly regarding reflections (combfilters) that are always depending from the postion of ls and lp in the room
If you choose your listening position regarding a good even bass response you have to measure at point between the speaker and lp, where bass is very low. Now think what coneq will do...
You can´t take the room out of your speakers.
So one have to be very careful what to correct exactly.
I thought a lot about this kind of correction system. I see no sense in doing it like coneq ...
Better use it as a normal room eq, I think.
Also prices for the measurement software are very high, and everytime you change only a little bit you have to measure again.
