range of the system down to 32Hz.
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. A vent with a progressive profile allows
laminar airflow and reduces 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 SB18 cabinet is made of first grade
Baltic birch plywood to ensure maximum acoustical and mechanical integrity.
The SB18 enclosure is driven and amplified by the LA4 or the LA8 controller. These ensure linearization, protection and
optimization for the loudspeaker system in the different operating modes of the SB18, cardioid included.
SB18 / SB18i / SB18m
In this document, the SB18 term and illustration will refer equally to SB18, SB18i or SB18m. These products
are different versions of the same subwoofer and share the same operating modes, presets and
recommended configurations. The rigging system of each version has been designed to be compatible with a
distinct main system: SB18 with KARA
