The VIO S318 is a one-of-a-kind triple 18” active subwoofer, designed to deliver unparalleled low-frequency power and precision phase response. As part of the VIO series, this subwoofer maximizes frontal emission and bass extension, making it an ideal choice for large-scale touring and sound reinforcement applications.
At its core, the VIO S318 houses three 18” bass-reflex half-horn loaded woofers, mechanically aligned for perfect phase coherence. Powered by three Digipro® G3 Class-D amplifiers, the system delivers 2700W RMS (5400W peak power), ensuring deep, impactful bass down to 35 Hz with a maximum SPL of 143 dB.
The integrated DSP module includes selectable crossover settings (70-105 Hz + Full Range) and an internal delay function (0-9.9 ms, adjustable in 0.1 ms steps), allowing for seamless system integration. Users can fine-tune input attenuation, polarity, and cardioid mode for optimal low-frequency management. The RDNet connectivity provides real-time remote control and monitoring, ensuring flexibility and precision in any setup.
Built for tour-grade durability, the multiplex plywood enclosure is reinforced with a Polyurea coating, ensuring resistance to wear and impact. The cabinet features five aluminum handles per side for easy transportation. Additionally, users can mount wheels on the rear panel or transport up to three units simultaneously with the DO-VIOS318 dolly system.
