The L-Acoustics KS28 is a high-performance dual 18-inch subwoofer designed for modern touring and demanding installations. Delivering deep, musical low end with exceptional headroom, it maintains precision and impact even at high SPLs, reaching confidently into the infrasonic range. Engineered to partner seamlessly with L-Acoustics line arrays such as K1 and K2, the KS28 integrates with LA12X and compatible amplified controllers via dedicated presets for consistent voicing and predictable coverage from venue to venue.
Built for the road, the robust enclosure features ergonomic handling and stack-friendly geometry for rapid deployment and efficient truck pack. The KS28 supports both standard and cardioid configurations, enabling precise low-frequency pattern control to reduce on-stage spill and minimise unwanted reflections. Suitable for ground-stacked or flown systems, it scales effortlessly from arenas and festivals to theatres, houses of worship and other large-format venues where controlled, extended sub-bass is essential.
Choose the KS28 when you need tight, impactful low-frequency reinforcement that complements high-output arrays without compromising clarity—ideal for touring providers, rental fleets and permanent installations seeking rider-approved performance.
