PACO-SB is a compact cardioid subwoofer for the PACO system, offering 30–200Hz low-end extension. It features passive cardioid design—no extra amp channels needed—for strong rear rejection and reduced group delay. The cabinet uses 18mm birch plywood with waterproof polyurea coating, built for touring. With a 3-point rigging system and ergonomic handles, it’s ideal for fast setup.
