The KS28 is L-Acoustics’ reference subwoofer for large format systems, designed to extend the frequency response of your setup. It features two high excursions, 18″ direct radiating transducers in a bass reflex tuned enclosure, which together deliver high SPL with low distortion. The optimized L-Vents laminar vented port also reduces turbulence and port noise at high levels while increasing LF efficiency. This enclosure utilizes the LA12X amplified controller power, ensuring advanced crossover functions, linearization and L-Drive protection of the transducers. Additionally, the optimized L-Vents laminar vented ports reduce turbulence and port noise, making the KS28 ideal for live sound reinforcement, theatres, and other fixed installations.

The Baltic beech and birch plywood enclosure is constructed with premium grade materials and features laminar vents for increased efficiency. And with six ergonomic handles, two stacking runners, and matching top tracks, the KS28 is easy to transport and set up.
