The L-Acoustics SB28 is a high-output dual 18-inch subwoofer engineered for deep, precise low-frequency extension in large-scale reinforcement. A refined bass-reflex design with optimised airflow delivers authoritative punch and clarity with low distortion, maintaining musicality even at very high SPL. Tuned to integrate seamlessly with L-Acoustics K and V series, it supports factory presets for standard and cardioid modes, enabling tight coverage with significantly reduced rear radiation for stages and noise-sensitive areas. The robust touring-grade enclosure features integrated rigging and stacking options, and is fully compatible with LA Series amplified controllers for consistent processing, protection and system management. Equally at home ground-stacked or flown, the SB28 scales effortlessly from festivals and arena tours to theatres and premium installations, providing reliable, impactful sub-bass that stays controlled across the venue. Ideal for concert PA, touring and rental fleets, and high-spec installed sound where dependable, clean low-end performance is essential.
