The L-Acoustics KS21 is a compact, high-performance 21-inch subwoofer engineered for fast, musical low-frequency extension with impressive headroom.

Integration is straightforward via LA Controller presets, ensuring consistent, repeatable results across touring, corporate and installed applications. Flexible deployment options include ground-stacked, flown and cardioid configurations (with multiple enclosures) to minimise stage spill and optimise audience coverage. Built to withstand the demands of professional use, the KS21 balances output, portability and rigging efficiency to keep load-ins swift without compromising sound quality. These pre-owned units are in great condition and remain a dependable, rider-friendly choice for production companies, rental houses and venues seeking compact sub-bass that punches well above its size. Ideal where clarity, impact and controlled low-frequency directivity are essential, from live music and theatre to corporate presentations and high-spec installations.
