Behringer SUPER-X PRO CX2310 V2 Crossover Confirmed to be in good working order. This is a later model, so it's still very usable. The connectors and knobs are also in very clean condition. Please note that there are very small scratches from being put in and taken out of a rack. It was stored in an indoor studio, so there's no worry about rust or mold. It's not just a channel divider that separates low and high frequencies; it also has a mono subwoofer output, which is useful if you want to add just one subwoofer to your studio monitor setup.
