Description
The DAS Audio MARA-SUB was developed as a powerful low-frequency extension for the MARA line array system. This self-powered cardioid subwoofer combines a large 21-inch front driver with an 18-inch rear driver, achieving not only high output but also highly controlled dispersion.
The front of the MARA-SUB features a 21-inch 21LFN driver with a 4-inch voice coil. At the rear is an 18-inch 18UXN cardioid driver, also with a 4-inch voice coil. Both drivers operate in a bass-reflex configuration. The rear driver, together with the DSP, provides the system’s cardioid operation.
The MARA-SUB has a frequency range of 32 Hz to 125 Hz (-10 dB). The system reaches a maximum linear SPL of 137 dB and a maximum SPL of 141 dB. This makes the MARA-SUB a powerful low-frequency foundation for the MARA-80 and MARA-100 line array systems.
The built-in Class-D amplifier features four bridged channels and delivers a total of 2,400 W RMS continuous and 4,800 W peak power. Power is distributed between the front and rear drivers. The switch-mode power supply is equipped with Power Factor Correction (PFC) for efficient and stable operation.
One of the key features of the MARA-SUB is its cardioid design. Thanks to the combination of the rear 18-inch driver and integrated DSP, rearward energy can be rejected by up to 14 dB in the 32 to 125 Hz range. This helps limit unwanted low frequencies toward the stage and ensures more controlled bass reproduction.
The MARA-SUB is equipped with FIR/DSP technology and ALMA control, allowing the system to be professionally configured, monitored, and managed. The sample rate is 96 kHz.
For touring and fixed installations, the subwoofer features an integrated Captive Rigging System. This allows the MARA-SUB to be flown alongside MARA systems using a single support system. The enclosure is made of high-quality birch plywood and finished with durable ISO-flex Paint. The metal grille features acoustically transparent and moisture-resistant fabric.
With a weight of 107 kg and dimensions of 605 × 1,070 × 790 mm, the MARA-SUB is a professional high-output subwoofer system for demanding PA, touring, and event applications.
