KS28 SUBWOOFER
Product Info
The KS28 is a reference subwoofer designed to extend the frequency response of large format systems. It features two high excursion, 18in 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 down to 25Hz. 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 on-board library offers standard and cardioid presets, each available with two low-pass filters to accommodate various coupling conditions and LF contour requirements.
