Overview
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) or 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.
