The PR Sub is a subwoofer for sound reinforcement consisting of a heavy-duty 15" woofer in a vented enclosure. The lightweight-yet-rugged injection-molded plastic enclosure with molded-in stand-mount cup facilitates portable use for augmenting the bass for live music, DJ use or speech. A black powder-coated steel grille provides driver protection and a professional appearance. The PR Sub speaker system is rated at 400 Watts program power handling, and the woofer features a 2 3/8" diameter voice coil and a 50 oz. magnet for excellent long term reliability. Two 1/4" phone jack input connectors make hook-up and daisy-chaining to other speakers a breeze.
