L ACOUSTICS - SB28 - High-pover subwoofer (New)
SB28
High-Power Subwoofer
- 25Hz LF limit, exceptional power handling capability
- Progressive vent for increased peak SPL, and minimal turbulence noise
- LA8 amplified controller drive and protection
- DSP presets for cardioid mode (symmetrical and asymmetrical)
The SB28 enclosure is a recommended subwoofer companion for the K1, KUDO®, V-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 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 overexcursion protection of the transducers. The L-ACOUSTICS® LA8 amplified controller offers the following drive modes:
- The ‘‘standard’’ mode using SB28 as a companion to K1, KUDO®, V-DOSC® and ARCS®, featuring a low-pass filter at 60 Hz ([SB28_60] preset) or closely coupled to ARCS® with a low-pass filter at 100 Hz ([SB28_100] preset)
- The ‘‘cardioid’’ mode using SB28 as a companion to K1, KUDO®, V-DOSC®, and ARCS®, featuring a low-pass filter at 60 Hz ([SB28_60_C] preset) or closely coupled to 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.
