The L-Acoustics SB28 is a dual 18-inch, high-power subwoofer engineered for precise, extended low-frequency reinforcement in both touring and installed sound. Its optimised bass-reflex enclosure features progressive-profile ports to minimise turbulence at very high SPLs, preserving punch, clarity and a linear response into the lowest octave. Efficient transducers and robust thermal management reduce power compression, ensuring consistent headroom and tonal stability over long shows and demanding environments.
When paired with LA8 amplified controllers, the SB28 benefits from dedicated protection and voicing, plus cardioid presets that deliver excellent rear rejection for cleaner stages and more controlled coverage. It integrates seamlessly with L-Acoustics full-range systems and scales predictably from single cabinets to large arrays, delivering reliable coupling and repeatable deployment. A rugged, tour-ready cabinet supports both flown and ground-stacked configurations, with practical ergonomics that speed up handling and setup.
From arenas and outdoor festivals to theatres, houses of worship and premium clubs, the SB28 provides authoritative, tightly controlled low end that professionals can trust for impactful bass and confident system control.
