The L-Acoustics SB28 is a dual 18-inch, high-power subwoofer engineered for precise, extended low-frequency reinforcement in touring and installed audio. Its optimised bass-reflex enclosure and progressive-profile ports minimise turbulence at very high SPLs to preserve attack, clarity and consistency down to the lowest octave. High-efficiency transducers and robust thermal management resist power compression, maintaining stable headroom and tonal balance throughout long performances. When paired with LA8 amplified controllers, dedicated presets provide protection and voicing, plus symmetrical and asymmetrical cardioid options for excellent rear rejection and cleaner stages. The rugged cabinet supports flown or ground-stacked deployment and integrates seamlessly with L-Acoustics full-range systems, delivering predictable, repeatable results across a wide variety of venues. From arenas and outdoor festivals to theatres and premium clubs, the SB28 supplies authoritative bandwidth, control and impact that underpin modern sound reinforcement. Choose it when you need powerful, accurate sub-bass with flexible configuration and consistent results, show after show.
