The L-Acoustics SB28 is a high-performance dual 18-inch subwoofer designed to deliver deep, precise low-frequency reinforcement for large-format PA systems. Its optimised bass-reflex enclosure pairs robust transducers with carefully managed airflow to achieve tight, musical bass, excellent transient response and generous headroom. Seamless integration with L-Acoustics amplified controllers provides consistent voicing, system protection and ready-to-use array presets, supporting both standard and cardioid deployments for enhanced directivity and superior stage rejection.
Engineered for touring reliability, the SB28 features a rugged enclosure and well-considered stacking and rigging options, enabling rapid, repeatable deployment from compact ground stacks to large-scale arrays for arenas and outdoor events. Thermal and airflow design helps maintain stable performance under sustained programme material, ensuring impactful, controlled low end for live music, dance applications and cinematic content. Whether used as standalone units or combined in scalable arrays, the SB28 underpins full-range systems with authority and control.
Ideal for touring PA, festivals, arenas, theatres and high-spec installations where extended low-frequency extension, consistent coverage and dependable day-to-day operation are essential.
