L-Acoustics SB28 Subwoofer
The SB28 enclosure is a recommended subwoofer companion for the KUDO®, V-DOSC®, dV-DOSC, and ARCS® systems, lowering the combined system operating range down to 25 Hz.
The SB28 contains two 18’’ direct radiating LF transducers integrated into a bass-reflex tuned enclosure. The specially designed 18’’ transducers provide an exceptional cone excursion capability combined with low thermal compression even at the very highest operating levels. The bass-reflex vents feature a progressive profile allowing for laminar airflow. The association of the modern components with the new vents delivers a greatly improved +5 dB peak SPL output compared to the previous standards.
The control and amplification of the SB28 is managed by the LA8 platform. The DSP filtering encompasses advanced crossover functions, system EQ, and L-DRIVE thermal and over-excursion protection of the transducers. The L-ACOUSTICS® LA8 amplified controller offers the following drive modes:
• The ‘‘standard’’ mode using SB28 as a companion to KUDO®, V-DOSC®, dV-DOSC and ARCS®, featuring a low-pass filter at 60 Hz ([SB28_60] preset) or as a companion to dV-DOSC and ARCS® with a low-pass filter at 100 Hz ([SB28_100] preset)
• The ‘‘cardioid’’ mode using SB28 as a companion to KUDO®, V-DOSC®, dV-DOSC, ARCS®, featuring a low-pass filter at 60 Hz ([SB28_60_C] preset) orhttp://www.gearsource.com/index.cfm/admin/stockitems as a companion to dV-DOSC, ARCS® with a low-pass filter at 100 Hz ([SB28_100_C] preset).
The performance of the SB28 enclosure depends upon the choice of preset and physical system configuration.
Made of high grade Baltic birch plywood, the cabinet also features industry standard aeroquip rails for line array rigging.
