DB Technologies Vio S318 - 2700W 3 x 18-inch Powered Bass Reflex Subwoofer with 4-inch Voice Coil in Black Finish

The dB Technologies Vio S318 is a powerhouse subwoofer, designed to extend the low-frequency performance of the Vio series with its extraordinary triple 18-inch woofer configuration. Offering an unmatched level of frontal emission and phase coherence, the Vio S318 is engineered to deliver exceptional performance in large-scale sound reinforcement applications. With its advanced design and powerful output, this subwoofer is capable of producing deep, low-end frequencies, reaching down to 35 Hz, making it the ideal complement for any large Vio system deployment.

The Vio S318 is equipped with three 18-inch bass reflex semi-horn loaded woofers, arranged to maximize frontal emission and ensure perfect phase response. The alignment of the voice coils creates a coherent low-end output, delivering a massive SPL of up to 143 dB. The system is powered by three Digipro G3 Class D amplifiers, providing a total of 2700W RMS power, with a peak output of 5400W. This power ensures that the Vio S318 can handle even the most demanding sound reinforcement needs, providing deep, powerful bass that fills large spaces with ease.

The Vio S318 also features an integrated DSP controller, offering users full control over the system's performance. It includes an on-board delay module that allows for up to 9.9ms of delay, adjustable in 0.1ms steps, ensuring perfect time alignment. The subwoofer also includes a cardioid array preset, enabling optimal rear sound rejection in cardioid configurations. Additionally, the system features a built-in crossover module, which allows for seamless integration with high-pass and low-pass filters, providing precise control over frequency output and further enhancing its versatility in various setups.

The subwoofer's robust multiplex plywood housing is reinforced with a durable polyurea finish, making it highly resistant to the rigors of touring and outdoor use. The cabinet is equipped with 4 aluminum handles on each side, ensuring easy handling during transport and setup. For added convenience, the Vio S318 is compatible with the DO-VioS318 dolly system, allowing users to transport up to three subs simultaneously. Alternatively, wheels can be mounted directly on the rear side of the cabinet for simple mobility.
