SB18 SUBWOOFER ENCLOSURE

The SB18 is the recommended subwoofer for modular WST
the operating frequency range of the system down to 32Hz.
The SB18 features one 18" neodymium speaker in a dual bass-reflex tuned enclosure. It provides impact, sensitivity,
low thermal compression and reduced distortion. One of the vents features a progressive profile allowing laminar
airflow and reduced turbulence noise, even at the highest operating levels. These combined properties contribute to
the sonic qualities of the SB18 in terms of precision and musicality. The cabinet is made of first grade Baltic birch
plywood to ensure maximum acoustical and mechanical integrity.
A 4-point rigging system is integrated into the cabinet and allows SB18 subwoofers to be flown or ground-stacked, as a
standalone array or within a vertical SB18/KARA array. The cabinet also features a pole mount socket for one XT or
two KIVA enclosures.
The SB18 is driven and amplified by the LA4X or the LA8 controller. These ones ensure linearization, protection and
optimization for the loudspeaker system in its different configurations, cardioid included
