The L-Acoustics SB28 is a dual 18-inch, high-power touring subwoofer designed for precise, extended low-frequency reinforcement. Its optimised bass-reflex enclosure uses progressive-profile ports to minimise turbulence at high SPL, preserving impact and clarity while maintaining a smooth, linear response into the lowest octave. High-excursion drivers and robust thermal management reduce power compression for consistent tonality and dependable headroom on demanding shows.
Seamless integration with LA8 amplified controllers delivers factory presets, advanced protection, and straightforward cardioid configurations for strong rear rejection and cleaner stages. SB28 arrays scale predictably from single units to large deployments, with options for ground-stacking or flying to suit production needs. A rugged cabinet, proven rigging, and road-ready hardware enable fast, repeatable setup for touring and large-format installations.
Ideal for arenas, outdoor festivals, theatres, houses of worship, and premium clubs, the SB28 provides authoritative, tightly controlled low end trusted by touring engineers when impactful, consistent bass is essential.
