DB Technologies Vio S118R - 1600W 18-inch Powered Bass Reflex Flyable Subwoofer with 4-inch Voice Coil and RDNet in Black Finish

The dB Technologies Vio S118R is a powerful 1600W 18-inch powered bass reflex flyable subwoofer, designed to extend the low-frequency response of the Vio line array systems. Equipped with a high-performance 18" neodymium woofer, the Vio S118R delivers precise, deep bass that integrates seamlessly with Vio arrays, making it an essential addition to any large-scale sound reinforcement setup.

At the heart of the Vio S118R is the advanced Digipro G4 Class D amplifier, which provides 1600W RMS and 3200W peak power. This next-generation amplifier includes Power Factor Correction (PFC) and a switched-mode power supply (SMPS), ensuring stable performance even in environments with fluctuating line voltages. The amplifier is complemented by a sophisticated DSP, allowing precise control over audio performance, including onboard delay adjustment, phase inversion, and cardioid array configuration for optimal rear sound cancellation in cardioid setups.

The Vio S118R comes equipped with an RDNet expansion card as standard, enabling full remote control and system monitoring via Aurora Net. The onboard slot also allows for future expansion with the optional Dante card, making this subwoofer ready for digital audio network integration. A real-time system auto-test feature enables quick diagnostics of both electronics and transducers, accessible either remotely via Aurora Net or directly from the amplifier module.

Designed for ease of use, the Vio S118R features onboard controls for input attenuation, delay, polarity, crossover frequency, and cardioid mode selection, all accessible via rotary encoders. The subwoofer's enclosure is built from rugged multiplex plywood, finished with a durable Polyurea coating to withstand the demands of touring and installation environments. Integrated rigging points and M20 pole mounts allow for flexible deployment in both flown and groundstacked configurations, while the included raincover ensures protection during outdoor use.
