Its rugged cabinet features comfortable, recessed metal bar handles, a 16-gauge perforated steel grille, rubber feet, and protective metal corners. Finished with impact-resistant black carpet. Input connectors include two 1/4" metal phone jacks and a genuine Neutrik NL4 connector. A polemount adapter allows the B-52 MX-15 to play above a crowd with strong projection, whether mounted on a speaker stand or a subwoofer.
