The L-Acoustics SB28 is a high-output touring subwoofer engineered for precise, musical low-frequency reinforcement. Twin 18-inch, high-excursion drivers work within an optimised bass-reflex enclosure featuring progressive-profile ports, reducing turbulence and port noise to preserve definition and fast transient response down to the lowest octave. Advanced thermal management minimises power compression, ensuring consistent performance over long shows and demanding programme material.
Seamless integration with LA8 amplified controllers provides validated presets for predictable results, coherent voicing and fast deployment. The SB28 supports cardioid and hypercardioid arrays for strong rear rejection, improving stage clarity and limiting spill in reflective or noise-sensitive spaces. Rugged construction with proven rigging options enables reliable flown or ground-stacked setups, ideal for intensive touring and rental use.
From theatres and houses of worship to arenas, premium clubs and outdoor festivals, the SB28 delivers authoritative, controlled bass with the headroom and accuracy required for modern large-scale sound reinforcement.
