Yes the DCX2496 is a GREAT product. Buy you should test your room first. Maybe you do not need an EQ (
this is my case). I bought an EQ and after some try out with speaker placement, I resolve 95% of my peeks. So, make some mesurement with REW and then make your decision.
There is some nice amp that have a built in parametric EQ. I am considering the
Crown XTI2000.
But if you want to drive your sub in real stereo, I think you will need a xover anyway...
