description

MARA-SUB is a self-powered cardioid subwoofer system that incorporates a front 21” speaker and a rear 18” speaker, both with a 4” voice coil, in a bass-reflex configuration. The rear 18” speaker creates the cardioid dispersion pattern needed to compensate for unwanted energy at the rear.

The Class D amplifier of the MARA-SUB has 4 bridged channels, providing power to both the front 21” speaker and the rear cardioid 18” speaker. The switched-mode power supply features power factor correction, reducing power consumption and improving reliability and consistency under all operating conditions. The built-in DSP optimizes the signal parameters for the speakers, allowing compensation of 14 dB of rear energy in the range of 32 Hz – 125 Hz.

The enclosure design adheres to DAS’s strict standards regarding the use of birch plywood and durable ISO-flexTM exterior protection. The MARA-SUB features the necessary rigging system to fly together with the MARA systems using a single support. The metal grilles include acoustically transparent and moisture-repellent fabric. Recessed handles are located on each side of the enclosure.
