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 re
