The L-Acoustics SB28 is a dual 18-inch touring subwoofer engineered for precise, extended low-frequency reinforcement at very high SPL. Its optimised bass-reflex enclosure with progressive-profile ports reduces 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 help minimise power compression, ensuring consistent tonality and reliable headroom throughout long performances.
Designed to integrate seamlessly with LA8 amplified controllers, the SB28 benefits from factory presets, advanced protection and rapid deployment of cardioid or hypercardioid arrays for excellent rear rejection and cleaner stages. It scales predictably from single units to substantial ground-stacked or flown arrays, making it a dependable choice for both touring and fixed installations. Rugged construction, proven hardware and practical rigging options support fast, repeatable setups and a long service life in demanding environments.
Ideal for arenas, outdoor festivals, theatres, houses of worship and premium clubs, the SB28 delivers authoritative, tightly controlled low end wherever impactful, consistent bass is essential.
