L-Acoustics KS28 Subwoofer
Description
Currently only located on the west coast.
The KS28 Flyable Subwoofer is a passive subwoofer with two high-excursion, direct-radiating 18 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 enclosure front is protected by a coated steel grill and an acoustically transparent fabric. The enclosure integrates six ergonomic handles, two stacking runners and matching top tracks for easy enclosure alignment. The Flush-fitting captive hardware allows for rigging and combining with other loudspeakers of the same family. 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.
