SARA-SUB is a high-fidelity subwoofer that offers an accurate and powerful bass response thanks to its cardioid design. The system incorporates a DAS 18UXN neodymium loudspeaker with a 4″ voice coil for excellent low-frequency reproduction. In addition, a rear 15FWN neodymium 3″ voice coil speaker creates the necessary cardioid dispersion pattern to compensate for unwanted energy in the rear.

The SARA-SUB’s built-in class D amplifier has 4 channels in bridge mode for each of the speakers. The switch-mode power supply has a correction factor, allowing for greater efficiency and reliability under all operating conditions. The built-in DSP optimizes the signal parameters for the loudspeakers and allows for 14 dB of rear power compensation in the 40 Hz – 80 Hz range.

The enclosure design meets the strict DAS standards for the use of high-quality materials, such as birch plywood and ISO-flex™ exterior protection. In addition, the rigging system allows the SARA to be flown underneath the SARA-SUB, using the JP-SARA. The metal grids incorporate acoustically transparent, moisture-repellent fabric. Recessed handles on the sides of the enclosure facilitate transport and handling.
