dBTechnologies SUB 915 15” Active PA Subwoofer

The SUB 915 from dBTechnologies’ SUB 900 series is a premium active subwoofer engineered to deliver full-bodied and powerful low-end response for professional audio environments. Housed in a bass-reflex plywood cabinet, the SUB 915 features a 15-inch woofer powered by a 900W RMS Class D Digipro G3 amplifier, capable of delivering high sound pressure levels up to 133 dB.

Ideal for ground-stacked applications, this subwoofer has been designed with flexibility and remote control in mind. 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. The back panel supports optional wheel mounting for easier transportation, and the total weight remains manageable at 34.8 kg.
