The Corps Design Large Tilting Speaker Frame features a locking tilt mechanism to position your field PA for maximum effect. Both decks are 30” x 30” to support large subwoofer and main speaker configurations. Both decks are covered with all-weather carpet. The upper deck has a safety stop in case an over-enthused band member attempts to adjust it while it is loaded! The back support struts are spaced to accommodate rack rails. All stress points are welded 360° and ground flush. The frame is powder coated for a superior, long-lasting finish.
