    Handle Your Success

    B-52’s enhanced-grip metal handles are the ultimate solution for carrying your B-52 loudspeakers. Constructed of bullet-proof stamped steel with a pressure-sensitive rubber backed grip, these handles are specially designed to fit in the palm of your hand.

    Elliptical Wave Guide

    B-52’s new waveguides are a perfect complement to the COMP-4 compression driver. The coverageis uniform over more than 3 octaves and the overall response is smooth and extended. The asymmetrical shape allows close physical coupling to the woofer and a slight tilt of the sound down to listening level.

    Flange Ports Increase Efficiency

    All SL-Series full-range systems utilize the COMP-4 1” exit pure titanium compression driver. The COMP-4 provides smooth mids and extended high-frequency reproduction.
