LARA-SUB

description

The LARA-SUB is a powered cardioid subwoofer system incorporating 2 DAS 18UXN neodymium low frequency transducers with 4” voice coils in a bass-reflex configuration. A single rear-facing 18UXN is used to create the cardioid dispersion pattern avoiding unwanted energy behind the system.

Powering the LARA SUB is a 3 channel Class D amplifier with independent channels powering each of the front-loaded low frequency transducers and the rear facing cardioid speaker. The amplifier´s regulated switch mode power supply is equipped with power factor correction reducing power consumption while enhancing reliability and consistency in all operating conditions. The onboard DSP optimizes the signal parameters for front and rear drivers to maximize the rear rejection 14 dB from 40 Hz – 80 Hz average.

Cabinet construction follows DAS´s strict construction standards employing birch plywood and the durable ISO-flexTM protective exterior coating. The LARA SUB incorporates captive rigging hardware that makes use of the common LARA rigging bumper, only one bumper type is needed to fly either LARA ARRAY or LARA SUB. The protective metal grilles are backed using acoustically transparent and water repellent fabric. Two recessed handles are located on each side of the enclosure.
