The L-Acoustics SB28 is a dual 18-inch high-power subwoofer designed for precise, extended low-frequency reinforcement in demanding touring and installation environments. Its optimised bass-reflex enclosure uses progressive-profile ports to minimise turbulence at extreme SPLs, preserving punch, definition and a linear response into the lowest octave. High-efficiency transducers and robust thermal management reduce power compression, maintaining consistent headroom and tonal balance over long performances.
Seamless integration with L-Acoustics LA8 amplified controllers provides dedicated presets for protection and voicing, including symmetrical and asymmetrical cardioid modes for effective rear rejection and cleaner onstage conditions. The rugged cabinet supports both flown and ground-stacked deployments, enabling flexible system design and predictable results alongside L-Acoustics full-range enclosures.
From arenas and outdoor festivals to theatres, houses of worship and premium clubs, the SB28 delivers authoritative bandwidth, control and impact. Choose it when you need accurate, reliable sub-bass performance that scales effortlessly to programme material and venue size.
