L-Acoustics SB18

High-power compact subwoofer

What is it?
A high-power, compact subwoofer designed to complement to L-Acoustics’ WST modular line sources and coaxial systems for applications requiring extended bandwidth with a flat to reinforced LF contour.

The SB18’s design is based on a single 18” LF transducer integrated into a dual bass-reflex tuned enclosure. Delivering useful output down to 32Hz, the SB18 is said to offer exceptional performance while providing the engineer and sound designer with a range of operating modes for rental and fixed installation applications. 18” transducers (specifically designed for the enclosure) combine high-excursion capability with thermal compression and reduced distortion. The bass-reflex vents feature a progressive profile said to allow laminar airflow and reduced turbulence noise, even at high operating levels.
