    How do you have it set up? Write down every setting for the crossover, EQ's, Comp/Lim, etc. that you put into it. Have you read the FAQ posts? Do that.

    Are you crossovers setup like I recommended here http://www.dbxpro.com/forum/viewtopic.php?t=884... If so you may want to try your LPF at 108 for your subs and HPF 111 for your tops... It would be much eaiser to keep all of this in one thread...I think...:)
