I know this is the wrong forum but I don't know if anyone visits the marketplace.

Anyone need to EQ their sub? Read on. I'd like to sell my Behringer Feedback Destroyer Pro/Parametric EQ DSP1124P to a worthy system. I'm simplifying mine. The BFD makes a nice parametric EQ for your sub. I'm sure it does more but that's what I used it for.

I've got one in perfect condition. Full instruction manuals and I'll include a 10ft Dayton sub cable, and 2 1/4"-to-RCA adapters (for input and output).

This is the BFD / This is the cable
(Maybe mine is 12', but you get the picture. Why quibble over two feet. It's a good cable)

There are set up guides on the web

I'm thinking $60 for all plus you pay shipping from central MA. PM me if interested.
