DB Technologies DVA S1518N - 1500W 18-inch Powered Band Pass Subwoofer with 4-inch Voice Coil in Black Finish

The DB Technologies DVA S1518N is a powerful 1500W 18-inch powered band pass subwoofer, designed to deliver deep, punchy, and precise bass for a wide range of professional audio applications. As an evolution of the DVA S10, the S1518N features a significant upgrade in power output, integrated DSP control, and full RDNet network capability, making it a highly versatile and efficient subwoofer for live sound reinforcement, concerts, and touring setups. With its robust 18-inch woofer and state-of-the-art Digipro G2 digital amplifier, the DVA S1518N ensures exceptional low-frequency performance, with a maximum SPL of 138 dB and a frequency range from 39 Hz to 120 Hz.

The heart of the DVA S1518N is its next-generation 18-inch woofer, equipped with a 4-inch voice coil that delivers powerful and responsive low-end sound. The subwoofer's band pass design enhances its efficiency and output, providing tight and punchy bass that transitions smoothly to the lower midrange frequencies of satellite speakers. This makes it an ideal match for pairing with DVA T12, T8, T4 units, or DVX Series enclosures. The subwoofer is designed for flexibility, whether used in compact ground-stacked configurations or flown in arrays using the optional SRK10 rigging hardware. The S1518N's ability to deliver consistent, high-quality bass makes it a perfect choice for medium to large venues and touring setups.

The integrated 1500W RMS Class D Digipro G2 amplifier provides ample power while maintaining high efficiency and reliability. The amp is equipped with a switched-mode power supply (SMPS) with Power Factor Correction (PFC), ensuring that the subwoofer is largely imperVious to voltage fluctuations, a critical feature for touring rigs where power conditions can vary. The convection cooling system ensures silent operation, even during extended use at high volumes, making the S1518N both powerful and reliable in demanding live sound environments.

One of the standout features of the DVA S1518N is its integrated 56-bit DSP processor, which offers extensive control over the subwoofer's performance. The DSP allows for precise limiter functions, variable crossover frequencies (75 Hz to 120 Hz in 5 Hz increments), and adjustable delay settings (0-4.5 ms) to ensure perfect time alignment with other speakers in the system. The subwoofer's phase can also be inverted (0° or 180°) to ensure optimal phase alignment in different configurations. The DSP includes a preset for configuring cardioid systems, allowing users to create directional subwoofer arrays that minimize rearward sound radiation and enhance front-facing bass output.

Network control is a key feature of the DVA S1518N, with full RDNet compatibility allowing for real-time monitoring and control of the subwoofer. This enables users to adjust settings such as EQ, delay, and system presets remotely, making the S1518N an ideal solution for large-scale sound systems where precise control and flexibility are essential. The subwoofer also features an X-Over output for simplified signal routing to satellite speakers, further enhancing the system's versatility and ease of setup.

The DVA S1518N is built with durability and practicality in mind. The subwoofer's housing is constructed from rugged multiplex plywood, finished with a protective coating to withstand the rigors of professional use. The rectangular design allows for easy stacking and transport, while the integrated rigging points provide secure attachment for flown configurations. The subwoofer is equipped with three handles on each side for easy handling, and an M20 pole mount allows for the attachment of satellite speakers, making it a versatile solution for both flown and ground-stacked setups.

In terms of portability, the DVA S1518N offers several optional accessories, including a dolly board with wheels for easy transport, a dust cover for protection during storage and transport, and a rain cover for outdoor use. The subwoofer's compact dimensions (515 mm wide, 640 mm high, and 720 mm deep) and weight of 46 kg (101.41 lbs) make it manageable for a subwoofer of its power and output, while its integrated hardware ensures that it can be easily incorporated into larger sound systems.

In summary, the DB Technologies DVA S1518N is a highly versatile and powerful 18-inch band pass subwoofer, delivering exceptional low-end performance, advanced DSP control, and network capability. Whether used in ground-stacked or flown configurations, the S1518N offers professional-grade sound reinforcement for live events, concerts, and large venues.
