The L-Acoustics SB28 is a dual 18-inch, high-power subwoofer designed to deliver precise, extended low-frequency reinforcement for touring and installation. Its optimised bass-reflex enclosure with progressive-profile ports minimises turbulence at very high SPLs, preserving attack, clarity and consistent response down to the lowest octave. High-efficiency transducers and robust thermal management resist power compression, maintaining headroom and tonal balance over long shows. When paired with LA8 amplified controllers, dedicated presets provide tailored protection and voicing, along with symmetrical and asymmetrical cardioid configurations for excellent rear rejection and cleaner stages. The rugged cabinet supports flown arrays and ground stacks, integrates seamlessly with L-Acoustics full-range systems, and ensures predictable, repeatable results across a wide range of venues. From arenas and outdoor festivals to theatres and premium clubs, the SB28 underpins modern sound reinforcement with authoritative bandwidth, control and impact. Choose it when you need powerful, accurate sub-bass with flexible deployment and consistent performance, show after show.
