The L-Acoustics KS21 Subwoofer Package supplies one compact, high-output 21-inch subwoofer complete with a fitted protective cover and a wheel dolly for smooth warehouse-to-venue moves. The KS21’s optimised vented design delivers fast, controlled low-frequency extension with ample headroom, ensuring tight, musical transients and seamless coupling with A Series, X Series and K Series tops. Cardioid configurations are supported to focus energy into the audience area, reducing onstage spill and improving clarity in reflective rooms. Full performance and protection are achieved when paired with L-Acoustics amplified controllers such as LA4X or LA12X for precise tuning and system management.
Built for real-world touring and rental use, the rugged enclosure and included accessories speed up load-ins, simplify handling on site and protect the cabinet in transit and storage. Scalable and reliable, this KS21 package integrates effortlessly into existing inventories and fixed installs where articulate, impactful bass and efficient deployment are essential. Ideal for live music, theatre, corporate events and clubs seeking refined low end with a minimal footprint.
