The KS28 is a reference subwoofer designed to extend the frequency response of large format systems. The KS28 features two high excursion, 18’’ direct radiating transducers mounted in a bass-reflex tuned enclosure. The optimized L-Vents laminar vented port reduce turbulence and port noise at high levels while also increasing LF efficiency.
The KS28 operates from 25 Hz. The excursion capability of the transducer, combined with L-Vents contributes to deliver a high SPL, with low distortion. The KS28 can offer standard or cardioid directivity, by combining physical deployment and the suitable preset.
The KS28 is the first L-Acoustics enclosure to fully utilize the LA12X amplified controller power. The LA12X ensures advanced crossover functions, linearization and L-Drive protection of the transducers. Its onboard library offers standard and cardioid presets, each available with two low-pass filters to accommodate various coupling conditions and LF contour requirements.
