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 L-Vents 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.
