I just upgraded to a receiver that handles multiple subwoofer EQ integration, so my Anti-Mode 8033 is for sale. This little guy will EQ multiple subs in your room. It's a Golden Ear award winner and has been received by the audio community with high acclaim. This specimen is in perfect condition, looks new, and I'll even throw in a splitter interconnect that will handle two subs. Comes with original shipping box. Pictures on request. $250 shipped CONUS.
