The L-Acoustics SB28 is a dual 18-inch touring subwoofer engineered for precise, extended low-frequency reinforcement at very high SPL. Its optimised bass-reflex enclosure employs progressive-profile ports to minimise turbulence and port noise, preserving transient punch and delivering a smooth, linear response down into the lowest octave. High-excursion transducers and robust thermal management limit power compression, maintaining consistent tone, headroom and impact throughout long shows.
Seamless system control is achieved with LA8 amplified controllers using validated presets for fast, predictable deployment. The SB28 supports cardioid and hypercardioid arrangements to maximise rear rejection, improving on-stage clarity and overall system control in acoustically challenging environments. Equally at home as single units, in substantial ground stacks or as flown arrays, it features proven rigging options and a road-ready build designed to withstand intensive touring schedules.
From arenas and outdoor festivals to theatres, houses of worship and premium clubs, the SB28 delivers authoritative, tightly controlled low end wherever impactful, consistent bass is essential.
