DB Technologies Vio S218 - 1600W 2 x 18-inch Powered Bass Reflex Subwoofer with 4-inch Voice Coil in Black Finish

The dB Technologies Vio S218 is a powerful 1600W dual 18-inch powered bass reflex subwoofer, designed to complement the Vio L212 line array system in large-scale sound reinforcement applications. Engineered to deliver an exceptional low-end response, the Vio S218 provides a frequency range extending down to 28 Hz, making it the perfect addition for those requiring a deep, impactful bass presence. This subwoofer's combination of dual 18" neodymium woofers, 3200W RMS Digipro G4 Class-D amplification, and advanced DSP control ensures it meets the most demanding audio needs with ease and reliability.

The Vio S218 is equipped with dB Technologies' advanced Digipro G4 amplifier technology, which delivers 3200W RMS power and features a full-range SMPS with Power Factor Correction (PFC). This makes the sub highly resistant to voltage fluctuations, ensuring consistent performance in a variety of environments. With integrated RDNet as a standard feature, users can monitor and control the system in real-time via Aurora Net software, making it ideal for professional installations and touring setups. The preamplifier also has a modular slot for future upgrades, including Audinate Dante AoIP, which allows for easy integration into digital audio networks.

The Vio S218 boasts innovative features designed for effortless use and superior performance. Near Field Communication (NFC) proximity sensors, combined with a high-brightness front LED, help users easily identify and configure each box within an array. An onboard system test provides quick diagnostics of both electronics and transducers, ensuring tour-grade reliability. The built-in cardioid stack preset allows for easy configuration of inverted gradient stacks, minimizing rear sound spill for optimal performance in challenging environments. Additionally, the onboard delay module offers up to 9.9ms delay with 0.1ms steps for perfect time alignment.

The rugged multiplex plywood housing, finished with Polyurea paint, provides durability for both touring and installation. The enclosure is equipped with 4 side handles for easy transport and rigging points to enable flown configurations with the DRK-210 rigging frame. The system also includes a raincover for outdoor protection.
