KS28 Package of 12 – Available in October 2025

Description

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-reex tuned enclosure. The optimized LVents laminar vented port reduce turbulence and port noise at high levels while also increasing LF efciency. 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 rst L-Acoustics enclosure to fully utilize the LA12X amplied 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 lters to accommodate various coupling conditions and LF contour requirements. The KS28 cabinet is assembled with birch and beech plywood panels. The use of panels optimized for thickness and combined with stiffeners gives the KS28 maximized internal volume, mechanical integrity and a low weight of 79 kg. It features six ergonomic handles for a solid grip and efcient handling. Bottom and side runners ensure safe stacking. A two-point suspension system is ush-mounted into the cabinet. The KS28 is the ideal companion to large format systems in stacked or own deployments. KS28 can signicantly boost the LF extension and contour of line sources. The KS28 can be stacked horizontally or vertically in standard or cardioid arrangements. With KS28-BUMP, KS28 can be own in vertical arrays of standard or cardioid arrangements, up to 16 units.
