The SB18 is the universal subwoofer designed for modular WST® line sources and coaxial systems, lowering the combined system operating range down to 32 Hz. Its compact size and integrated rigging make it extremely well suited for flown coupled configurations with KARA®. The association of a specifically designed 18’’ transducer with a dual bass-reflex tuned enclosure provides exceptional impact and high sensitivity, low thermal compression and reduced distortion. The vents feature a progressive profile allowing laminar airflow and reduced turbulence noise even at the very highest operating levels. These combined properties contribute to the sonic qualities of the SB18 in terms of precision and musicality. The control and amplification of the SB18 is managed by either the LA4 or LA8 (LA-RAK) platform. The onboard DSP filtering encompasses advanced crossover functions, system EQ, and dual thermal and over-excursion protection of the transducer. The L-ACOUSTICS® amplified controllers offer the following drive modes:
The performance of the SB18 enclosure depends upon the choice of preset and physical system configuration. Made of high grade Baltic birch plywood, the cabinet also features a pole mount socket for use with one XT or two KIVA enclosures. |

"The Chicago Auto Show was my first experience with SB18 and they were absolutely amazing. Their compact size and captive rigging made them extremely easy to fly and the sound was fantastic. I had quite a number of engineers handling other press events tell me after the show how good they thought everything sounded, especially the nice, tight bass. It was really quite remarkable how well the SB18s managed low end in the space." | ![]() |
