L-ACOUSTICS introduced the SB18 high power compact subwoofer Prolight + Sound 2010.
The SB18 complements L-ACOUSTICS WST (Wavefront Sculpture Technology) modular line sources and coaxial systems for applications requiring an extension of bandwidth with a flat to reinforced LF contour.
The SB18 delivers an exceptional level of performance while offering the engineer and sound designer numerous modes of operation for rental and fixed installation applications.
The main L-ACOUSTICS system components for LF extension and contour reinforcement are the SB18 subwoofer with a low frequency limit of 32 Hz and LA4 and LA8 (LA-RAK) amplified controllers.
The 18’’ transducers specifically designed for SB18 combine high excursion capabilities, low thermal compression and reduced distortion.
The bass-reflex vents feature a progressive profile allowing laminar airflow and reduced turbulence noise, even at the highest operating levels.
These combined properties contribute to the SB18 sonic qualities in terms of precision and musicality.
The SB18 design is based on a single 18’’ LF transducer integrated into a dual bass-reflex tuned enclosure to deliver both impact and high sensitivity. Its compact size, combined with superior damping characteristics, make it extremely well suited for compact FOH applications. The SB18 is particularly recommended for use with KARA (either coupled/flown or stacked configurations), KIVA, ARCS and coaxial LF contour reinforcement in both standard and cardioid modes.
