Hello Nick and welcome to the Shack!

Is there a particular reason you would want a DCX2496... I think maybe you intended to mean the DEQ2496. None the less... a DSP1124P would most likely do all you need and they can be purchased for $100 or less.

First things first though. Check out the REW Forum and read up on it, then download it and measure the response in your room. Let's see what you have to deal with before deciding what you need.
