You are in a bit of a stinky shaped room if it is 8x8. But go to the aforementioned site and read a BUNCH!!!
And also try two things with your ITB scenario.
Firstly take the above advice and try HPF ing or turning down any bass Freqs that are un needed. ( Probly ignore this on Bass Gat and Bass kik but again yr ears will tell ya if these guys NEED this treatment.
Secondly ( Big importance here). Dont run yr EQ's hot. Try and either trim the volume of yr tracks or if you have a dynamic device prior to any eq then back offa the output so's not to overshoot the EQ. ESOECIALLY offa you are adding top end.
But dollars to donuts your room size/shape and monitor placement will be more likely the villians than yr convertors.
