The DB Technologies DVA S1518N is a powerful 18" bandpass subwoofer offering a 1500W digital power amp, integrated DSP, RDNet link, and versatile rigging options. Its advanced design delivers tight bass, perfect for seamless transitions with satellite systems, making it ideal for various setups.
Powerful 18″ Woofer and Amplifier: The DVA S1518N features an 18″ woofer powered by a 1500W Digipro® G2 Class D amplifier. This combination delivers punchy, deep bass, perfect for any professional sound setup. The power amp increases output by 50% compared to the DVA S10, providing superior performance.
Integrated DSP with Advanced Control: Equipped with an integrated 56-bit DSP, the DVA S1518N offers variable crossover frequencies, adjustable delay, and precise limiter functions. These settings enable perfect time alignment and seamless transitions between subwoofers and satellite speakers. The DSP also allows for cardioid configuration presets and detailed system control.
RDNet Network Control: The DVA S1518N includes RDNet-enabled technology, which allows users to remotely control and monitor the subwoofer. This feature is particularly valuable for managing large sound systems in complex venues, ensuring optimal performance with minimal on-site adjustments.
Rugged Construction and Easy Rigging: Housed in durable multiplex plywood, the subwoofer is built to withstand rigorous use. It includes multiple handles for easy transportation. The optional SRK10 rigging hardware allows the subwoofer to be flown in arrays or paired with DVA T12, T8, T4, or DVX series enclosures for flexible system configurations.
Reliable Power Supply: With PFC switched-mode power supplies, the DVA S1518N is resilient to voltage fluctuations, ensuring consistent performance even in demanding touring conditions. This power supply ensures high efficiency and reliability across different power sources.
Safety Features: The subwoofer is equipped with RMS, peak, and thermal limiters, providing extra protection against damage during extended use. These safety measures enhance the durability and longevity of the equipment, even under heavy use.
