The L-Acoustics SB28 is a high-performance subwoofer engineered to deliver tight, powerful low-frequency energy for demanding professional sound reinforcement. Designed around dual high-excursion 18-inch drivers in a precision-tuned enclosure, it offers authoritative sub-bass extension with excellent transient response, making it a natural partner for modern line array and point-source systems. Its robust build and efficient airflow design help maintain consistent performance at high SPL, while the enclosure geometry supports cardioid and steered low-frequency configurations when used in appropriate arrays and processing setups.
Well suited to touring, festivals, arenas, and large-format installations, the SB28 provides both scale and control, ensuring punch and clarity from dance music to rock and orchestral applications. The included front-fit dolly streamlines transport and load-in/out, helping crews deploy more quickly and safely. If you need impactful, reliable low end that integrates seamlessly with premium L-Acoustics systems, the SB28 is a proven choice.
Ideal for touring sound, rental houses, and fixed installs requiring precise, high-SPL sub-bass.
