The L-Acoustics SB28 is a dual 18-inch, high-power subwoofer engineered for precise, extended low-frequency reinforcement in both touring and fixed installations. 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, keeping headroom and tonal balance stable over long shows. When paired with LA8 amplified controllers, dedicated presets deliver tailored protection and voicing, plus 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 provides authoritative bandwidth, control and impact to underpin modern sound reinforcement. Choose it when you need powerful, accurate sub-bass with flexible deployment and consistent performance, show after show.
