The L-Acoustics KS21 is a compact, high-output subwoofer designed for precise, musical low-frequency reinforcement with excellent control. Its premium 21-inch transducer in an efficient bass-reflex enclosure delivers deep extension and added headroom, seamlessly complementing L-Acoustics point source and line source systems such as the A Series and ARCS. Factory-optimised presets on L-Acoustics amplified controllers provide robust protection, phase-coherent integration and consistent, repeatable results across venues and deployments.
Engineered for both touring and fixed installations, the KS21 features rugged construction, integrated rigging options and a space-saving footprint for flexible placement on stage, flown with suitable accessories, or discreetly within visually sensitive environments. Used in multiples, it supports directional and cardioid configurations to minimise stage spill and tighten audience coverage, ensuring impactful, uniform bass performance.
From live music and theatre to corporate events and premium venues, the KS21 offers reliable, controlled low end with streamlined setup and predictable results.
