L-Acoustics KS28 ลำโพงซับวูฟเฟอร์


L-Acoustics 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.

Passive subwoofer with two high-excursion, direct-radiating 18 in transducers mounted in a bass-reflex tuned enclosure with laminar vents for increased LF efficiency. The enclosure cabinet is constructed of premium grade Baltic beech and birch plywood. The enclosure front is protected by a coated steel grill and an acoustically transparent fabric. The enclosure integrates six ergonomic handles, two stacking runners and matching top tracks for easy enclosure alignment. The Flush-fitting captive hardware allows for rigging and combining with other loudspeakers of the same family. Combining two or more elements with associated presets achieve omnidirectional or cardioid directivity patterns. Exclusively driven and protected by a proprietary amplified controller through a dedicated preset.
