Housing a premium 21-inch driver in an efficient bass-reflex enclosure, it seamlessly extends the bandwidth and headroom of L-Acoustics point source and line source systems, including the A Series and ARCS. Optimised presets on L-Acoustics amplified controllers ensure precise protection, phase-coherent integration and repeatable results across deployments.\n\nBuilt for touring and installations alike, the KS21 features robust construction, integrated rigging options and a compact footprint for flexible placement on stage, flown with appropriate accessories, or discreetly within visually sensitive spaces. When used in multiples, it supports directional and cardioid configurations to minimise stage spill and improve audience coverage, delivering impactful, consistent bass from show to show.\n\nFrom live music and theatre to corporate events and premium venues, the KS21 is a reliable choice where deep, controlled low end and streamlined deployment are essential.\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIncludes\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eL-Acoustics KS21 Subwoofer – Compact High-Impact Bass\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003csmall\u003e\u003cstrong\u003eSTAGE14.3.100.690\u003c\/strong\u003e\u003c\/small\u003e\u003c\/p\u003e","brand":"L-Acoustics","offers":[{"title":"New Equipment","offer_id":63735111352697,"sku":null,"price":4242.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0288\/2260\/1776\/files\/Photo-21.08.25-12-24-10-_E2_80_93-_CE_BC_CE_B5_CE_B3_CE_AC_CE_BB_CE_B7_3be95c26-0f4c-4e3b-bc4f-029ce2e741fa.jpg?v=1781088799","url":"https:\/\/stage-experts.com\/products\/stage14-l-acoustics-ks21","provider":"Stage Experts Ltd","version":"1.0","type":"link"}
