L ACOUSTICS - SB18iRAL - High power compact subwoofer (New)

High Power compact subwoofer

• 32 Hz LF limit, high power handling, low distortion and thermal compression
• Progressive vent for increased peak SPL, and minimal turbulence noise
• DSP presets for cardioid mode (symmetrical and asymmetrical)
• Pole mount for XT series, ARCS® WIDE/FOCUS and KIVA
• Compatible rigging : SB18(i)/KARA®(i), SB18m/ARCS® WIDE - FOCUS

The SB18i is the fixed installation subwoofer designed for WST® line sources and coaxial systems, lowering the combined system operating range down to 32 Hz. Its compact size and streamlined rigging make it extremely well suited for flown coupled configurations with KARAi®.

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 SB18i in terms of precision and musicality.

The control and amplification of the SB18i is managed by either the LA4 or LA8 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 SB18i as a companion to KUDO®, KARAi®, KIVA-KILO, ARCS® and featuring a low-pass filter at 60 Hz ([SB18_60] preset) or closely coupled to KARAi®, ARCS® and XTi with a low-pass filter at 100 Hz ([SB18_100] preset).
• The ‘‘cardioid’’ mode using SB18i as a companion to KUDO®, KARAi®, KIVA-KILO, ARCS® and featuring a low-pass filter at 60 Hz ([SB18_60_C] preset) or closely coupled to KARAi®, ARCS® and XTi with a low-pass filter at 100 Hz ([SB18_100_C] preset).

The performance of the SB18i enclosure depends upon the choice of preset and physical system configuration. Made of high grade Baltic birch plywood, the cabinet features a pole mount socket for use with XTi or KIVA enclosures and standard M6 inserts for custom rigging options.
