L-Acoustics SB15m-RAL 15 Inch High Power Compact Subwoofer - RAL

Ultra-compact passive subwoofer with a high excursion, direct radiating 15 in transducer mounted in a 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 transducer front is protected by a coated steel grill and an acoustically transparent fabric. The enclosure integrates two ergonomic handles and a 35mm pole-mount socket. Two coupling bars allow 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. Exclusively driven and protected by a proprietary amplified controller through a dedicated preset.
