L-Acoustics SB18 High Power Compact Subwoofer 1x18-Inch

Compact passive subwoofer with a high-excursion, direct-radiating 18 in transducer mounted in a dual bass-reflex tuned enclosure with laminar vents for increased LF efficiency. The enclosure cabinet is constructed of premium grade Baltic beech and birch plywood. The enclosure front is protected by a coated steel grill and an acoustically transparent fabric. The enclosure integrates four ergonomic handles, and panel corner stops for enclosure protection. The captive hardware allows for rigging and combining with other loudspeakers of the same family. Dedicated rigging accessories allow for flown or stacked configurations. Combining two or more elements with associated presets achieve omnidirectional or cardioid directivity patterns.
