Thanks to RDNet protocol and Aurora Net software (compatible with Windows and Mac), users can perform real-time remote control and monitoring, customize delay settings, and match crossover frequencies with full-range systems enabled for RDNet communication.The SUB 915 offers onboard DSP controls, including a delay function adjustable up to 4.5 milliseconds in 0.5 ms steps directly on the unit, while the Aurora Net software extends this to 21 ms. A dedicated rotary allows users to set the crossover frequency from 70 Hz to 110 Hz for seamless integration with different speaker setups. Other controls include attenuation, polarity switch, and rotary controls for crossover and delay adjustments.Physically, the subwoofer is built from robust plywood, designed to operate vertically or horizontally. It includes integrated handles for portability and M20 mounting threads on both the top and side panels for versatile speaker setups.
