dB Technologies VIO S218 – Active Dual 18″ Bass-Reflex Subwoofer

The dB Technologies VIO S218 is a touring-class active dual 18″ subwoofer designed as the bottom-end complement to the VIO L212 line array. Two 18″ neodymium woofers with 4″ voice coils sit in a voluminous bass-reflex housing extending response down to 27 Hz, with cardioid stack presets for maximum cancellation in gradient inverted configurations.

Twin Class-D Digipro G4 amplifiers deliver a combined 3200W RMS for up to 143 dB SPL of impact. Onboard DSP, selectable crossovers, 9.9 ms delay, and full Aurora Net / RDNet integration make VIO S218 a precision tool for major sound reinforcement events.
