The L-Acoustics SB28 is a dual 18-inch touring subwoofer built for precise, extended low-frequency reinforcement at very high SPL. Its optimised bass-reflex enclosure uses progressive-profile ports to minimise turbulence and port noise, preserving transient impact and delivering a smooth, linear response deep into the lowest octave. High-excursion drivers and robust thermal management reduce power compression, so tone, punch and headroom remain consistent throughout long shows.
Seamless control is achieved with LA8 amplified controllers via validated presets for fast, reliable deployment and predictable system behaviour. The SB28 supports cardioid and hypercardioid configurations to maximise rear rejection, improving on-stage clarity and overall system control. Equally effective as single units, substantial ground stacks or flown arrays, it features proven rigging options and road-ready construction 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.
