Compact High-Power Subwoofer
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 ‘‘standard’’ mode using this subwoofer as a companion to KUDO, KARA®, KIVA-KILO, ARCS® and featuring a low-pass filter at 60 Hz ([SB18_60] preset) or closely coupled to KARA®, ARCS® and XT with a low-pass filter at 100 Hz ([SB18_100] preset).
- The ‘‘cardioid’’ mode using this subwoofer as a companion to KUDO, KARA®, KIVA-KILO, ARCS® and featuring a low-pass filter at 60 Hz ([SB18_60_C] preset) or closely coupled to KARA®, ARCS® and XT with a low-pass filter at 100 Hz ([SB18_100_C] preset).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.
