DB Technologies DVA S30 N - 3000W 2 x 18-inch Powered Bass Reflex Subwoofer with 4-inch Voice Coil in Black Finish

The DB Technologies DVA S30 N is a formidable 3000W dual 18-inch powered bass reflex subwoofer, specifically designed to deliver an incredibly powerful and low-frequency punch, making it the perfect addition to large PA systems. With its advanced hybrid design, which combines the benefits of both bass reflex and horn systems, the DVA S30 N is engineered to reproduce low frequencies with unmatched sound pressure levels and extended range. This makes it an ideal companion for DVA T12 mid-/high-range units in stacked arrays, providing a deep, muscular low-end that perfectly complements high-powered sound systems for concerts, festivals, and large-scale events.

The DVA S30 N features a dual 18-inch subwoofer configuration, with each woofer equipped with a 4-inch voice coil. These woofers are arranged within a hybrid bass reflex-horn housing, which is designed to maximize the output of low frequencies while maintaining excellent sound clarity. The baffle boards are positioned in a V-shaped configuration, which guides the sound energy from the central bass reflex channel into the horn's port, resulting in a smooth and uniform bass output that greatly extends the range and impact of the subwoofer. This unique design allows the DVA S30 N to deliver a tight, punchy bass response while maintaining high efficiency and sound pressure, with a maximum SPL of 141 dB and a frequency range from 30 Hz to 120 Hz.

The DVA S30 N is powered by a 3000W RMS Class D Digipro G2 amplifier, which provides the necessary power to drive both 18-inch woofers with precision and reliability. The amplifier is equipped with a 3 kW switched-mode power supply (SMPS), ensuring stable performance even in challenging power environments, making the subwoofer ideal for touring applications. The convection cooling system ensures quiet and efficient heat dissipation, allowing the subwoofer to perform consistently during extended periods of high-demand use. With its robust amplifier and innovative design, the DVA S30 N is capable of delivering powerful, distortion-free bass at high volumes, making it an essential component of any large-scale sound system.

The integrated 56-bit DSP processor provides comprehensive control over the DVA S30 N's performance, offering features such as variable crossover frequencies (adjustable from 75 Hz to 120 Hz in 5 Hz steps), precise limiter functions (RMS, Peak, and Thermal), and adjustable delay settings (0-4.5 ms) for perfect time alignment with other speakers in the system. The DSP also includes a preset for configuring cardioid systems, allowing users to reduce low-frequency sound behind the array while focusing bass energy toward the audience. This is especially useful in environments where controlling the dispersion of low frequencies is critical. The system's phase can be inverted (0° or 180°), ensuring proper phase alignment in different configurations, and the X-over output allows for easy integration with satellite speakers or line arrays.

As part of DB Technologies' network-enabled product line, the DVA S30 N is fully RDNet-compatible, allowing for remote control and monitoring via the RDNet network port. This enables users to adjust settings such as EQ, delay, and cardioid presets in real-time, providing maximum flexibility and control in large-scale sound systems. The onboard rotary encoder makes it easy to access and adjust system settings directly on the subwoofer, streamlining setup and configuration processes.

The DVA S30 N is housed in a rugged multiplex plywood enclosure, finished with a durable black textured lacquer that protects it from the wear and tear of professional use. The subwoofer's rectangular design allows for easy stacking in ground setups, and it is equipped with four handles per side for convenient transport and handling. The subwoofer also includes integrated rigging points, allowing it to be flown in arrays using the DRK10 or DRK20 rigging frames, making it a versatile solution for both ground-stacked and flown configurations. Optional accessories, such as a dolly board with wheels, dust cover, and rain cover, are available to further enhance portability and protection.

Measuring 1100 mm in width, 580 mm in height, and 720 mm in depth, and weighing 83 kg (182.98 lbs), the DVA S30 N is a powerful and robust subwoofer that is designed to deliver high-impact bass in both indoor and outdoor environments. Its large size and weight are a testament to its impressive output capabilities, making it an ideal choice for professional sound engineers and event organizers who require deep, powerful bass for large audiences.

In summary, the DB Technologies DVA S30 N is a high-performance, dual 18-inch powered subwoofer that offers powerful bass output, advanced DSP control, and network capability in a durable and versatile design. Whether used in ground-stacked or flown configurations, the DVA S30 N provides exceptional low-frequency reinforcement for large PA systems, making it a valuable addition to any professional sound setup.
