DB Technologies DVA KS20 - 1800W 2 x 18-inch Powered Bass Reflex Subwoofer with 4-inch Voice Coil in Black Finish

The DB Technologies DVA KS20 is a high-powered, dual 18-inch active bass reflex subwoofer designed to provide the ultimate low-end support for large DVA K5 systems. Engineered for versatility and powerful bass performance, this subwoofer is ideal for both horizontal and vertical ground-stacked configurations, making it perfect for large-scale sound reinforcement applications, such as concerts, festivals, and large venues. The DVA KS20 combines the benefits of both bass reflex and horn-loaded designs in a compact and robust housing, ensuring tight and punchy bass with high sound pressure levels, all within a durable structure capable of withstanding the rigors of professional use.

At the heart of the DVA KS20 are two 18-inch woofers, each equipped with 4-inch voice coils, delivering deep, powerful bass that reaches down to 41 Hz. The subwoofer's bass reflex design is paired with the efficiency of horn-loading, creating a system that can deliver maximum output while maintaining tight, controlled low-end frequencies. With a maximum SPL of 138 dB, the DVA KS20 ensures that even the largest venues will be filled with deep, impactful bass, making it an ideal choice for use in large event setups and professional audio applications.

Powered by two Digipro G3 Class D amplifiers, the DVA KS20 delivers an impressive 1800W RMS power and 3600W peak power, ensuring ample headroom and powerful low-end performance. The subwoofer's amplifier system is passively cooled via convection, providing efficient heat dissipation without the need for noisy fans. The power supply features an auto-range SMPS (Switch Mode Power Supply), which ensures stable power delivery and operational flexibility in various conditions.

The advanced 56-bit DSP processor inside the DVA KS20 provides comprehensive system control, allowing for seamless integration with other components in a larger sound system. The DSP manages limiters, delays, and crossover functions, ensuring smooth and flawless system processing. The subwoofer offers selectable crossover points at 90 Hz and 120 Hz, allowing users to tailor the low-end response to match the specific requirements of their sound system. The delay feature is adjustable up to 4.5 ms, in 0.5 ms increments, allowing for precise alignment of the subwoofer with other speakers in the system.

Versatility is one of the key features of the DVA KS20, allowing it to be used in a variety of configurations. The subwoofer can be ground-stacked either vertically or horizontally, and it is equipped with two pick points on top for rigging frames (compatible with DRK10/20), enabling the DVA KS20 to be securely flown in line array systems with DVA K5 modules. Additionally, the subwoofer includes an M20 pole mount on top, making it easy to mount full-range speakers or additional subs for a compact, powerful setup.

The DVA KS20 is housed in a rugged plywood enclosure, finished with a durable black lacquer coating that provides protection against the wear and tear of touring and live performances. The cabinet is equipped with three handles on each side, ensuring easy transport and handling despite its substantial weight of 84 kg (185.19 lbs). The robust design makes it suitable for both indoor and outdoor use, ensuring reliable performance in any setting. The subwoofer's input and output sections feature two XLR balanced connectors, providing flexible connectivity for integrating with other speakers or amplifiers in the system. The PowerCON input and output sockets ensure secure and reliable power connections.

In summary, the DB Technologies DVA KS20 is a powerful, versatile, and high-performance dual 18-inch subwoofer designed to deliver exceptional low-end reinforcement for large-scale sound systems. With its robust construction, advanced DSP processing, and flexible configuration options, the DVA KS20 is an ideal choice for sound professionals seeking deep, punchy bass for concerts, festivals, and other demanding audio environments.
