BBE Sonic Maximizer 2 way stereo/3 way mono crossover. Awesome addition to any PA system or bass rig. Used for about 2 hours. No dings or scratches. In original packaging with manual and power cord. Bought it to tweak my sound with a 15" cab and a 2X10" but to be honest I never had the time to spend to mess with it. Just looking to get what I paid. first 110 bucks plus shipping takes it.
