L-Acoustics SB6r-INCEILING Dual 6.5 Inch Ultra-Shallow Subwoofer – Recessed for Ceilings
Install-specific ultra-shallow passive subwoofer with two direct radiating 6.5 in transducers 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. Dedicated accessories allow for various mounting options: on-wall, on-ceiling, in-wall and in-ceiling. The inserts and the connectors are all gathered on a single enclosure panel. Exclusively driven and protected by a proprietary amplified controller through a dedicated preset.
