DB Technologies Vio S218F - 1600W 2 x 18-inch Powered Bass Reflex Flyable Subwoofer with 4-inch Voice Coil in Black Finish

The dB Technologies Vio S218F is a high-powered, flyable dual 18-inch bass reflex subwoofer, designed to extend the low-frequency performance of large Vio sound reinforcement systems. Equipped with cutting-edge technology and premium components, the Vio S218F delivers an ultra-low frequency punch, extending down to 28 Hz. This subwoofer is perfect for enhancing Vio systems in demanding sound reinforcement applications, including concert tours and large-scale events.

The Vio S218F features two 18-inch neodymium woofers, driven by a 3200W RMS Digipro G4 Class-D amplifier. This amplifier is equipped with a full-range SMPS with Power Factor Correction (PFC), ensuring the system remains highly resistant to line voltage fluctuations and capable of withstanding 380V power surges. The advanced DSP controller allows for precise control over sound reproduction, while the built-in RDNet card provides real-time remote control via Aurora Net software. Additionally, the Vio S218F is prepared for future upgrades, including integration with Audinate Dante AoIP protocol, ensuring the system remains future-proof.

The Vio S218F's flyable design allows up to 14 cabinets to be flown using the DRK-218F flybar, making it ideal for large venue setups. It also includes side-integrated rigging hardware for secure and flexible installation. Users benefit from on-board delay functionality, offering up to 9.9ms delay with 0.1ms steps for perfect time alignment, and the cardioid stack preset button, which enables optimal cancellation of rear sound in gradient inverted configurations. A clean cable management system ensures easy cable routing during setup.

Engineered for reliability, the Vio S218F includes an intelligent power-on sequence (IPOS) and an on-board system test for quick diagnostics, allowing users to monitor the performance of both electronics and transducers. Near Field Communication (NFC) technology and a high-brightness front LED assist in recognizing and configuring each subwoofer in an array, streamlining the setup process. Built for durability, the subwoofer is housed in a rugged multiplex plywood enclosure, finished with Polyurea coating to withstand the rigors of touring and outdoor environments.
