DB Technologies SUB 915 - 900W 15-inch Powered Bass Reflex Subwoofer with 4-inch Voice Coil in Black Finish

The dB Technologies SUB 915 is a high-performance 15-inch powered bass reflex subwoofer designed to deliver powerful low-end reinforcement for a wide range of applications. Whether used for live sound setups, fixed installations, or other professional audio systems, the SUB 915 is engineered to deliver deep, full-bodied bass with precise control. It's equipped with a premium 15" woofer and a 900W RMS Class-D Digipro G3 amplifier that provides exceptional efficiency and high sound pressure levels up to 133 dB, ensuring that it meets the demands of even the most challenging environments.

One of the standout features of the SUB 915 is its ability to be remotely controlled in real time via the RDNet protocol, using Aurora Net software available for both Windows and Mac platforms. This allows users to monitor and adjust performance, including DSP settings, from a remote location, enabling advanced subwoofer configurations and seamless integration with other dB Technologies full-range systems that also support RDNet communication. This ensures that the SUB 915 can be easily customized to fit the specific needs of any event or venue, offering flexibility and ease of operation.

The on-board control panel includes several key features that make the SUB 915 versatile and user-friendly. Users can easily adjust attenuation, select polarity, and fine-tune the crossover frequency with a rotary dial, allowing precise control over the subwoofer's low-end output. The built-in DSP also includes delay settings that can be adjusted up to 4.5 milliseconds in 0.5 ms increments directly on the unit, with extended delays of up to 21 milliseconds achievable via Aurora Net. This advanced functionality allows for perfect timing alignment in complex sound setups.

The robust plywood enclosure is built to withstand the rigors of frequent transport and live sound use, while maintaining a relatively lightweight design at 34.8 kg (76.7 lbs). Integrated handles on the top edges and a rear-mounted wheel option make transportation easy and efficient. The subwoofer is designed for both vertical and horizontal use, making it adaptable to different setup configurations, and it includes two M20 threaded pole mounts-one on the top and one on the side-allowing full-range speakers to be mounted securely in any orientation.
