DB Technologies DVA KS20 2x 18″ Active-Subwoofer

The DVA KS20 is the ideal low-frequency reinforcement for large-scale DVA K5 systems, delivering exceptional sound pressure levels and a robust frequency response in a flexible format. Designed for both horizontal and vertical groundstacked configurations, this active dual 18” subwoofer is built to meet the demands of modern touring and installation environments.

At its core, the KS20 features two 18” woofers housed in a hybrid bass reflex and horn-loaded design, combining the fast transient response of horn systems with the low-end extension and punch of bass reflex enclosures. This internal acoustic structure is paired with two Digipro® G3 Class-D amplifiers, providing a combined 1800W RMS / 3600W peak power and reaching a powerful 138 dB SPL.

The onboard 56-bit DSP manages advanced system processing including multiband limiters, selectable crossover frequencies (90/120 Hz), and a delay function adjustable up to 4.5 ms—ideal for aligning multiple subwoofers or full-range arrays. The system also includes a phase inversion switch and output mode selector (Link/X-Over) for complete tuning flexibility.

Connectivity is comprehensive with dual XLR inputs and outputs and PowerCON in/out sockets for daisy-chaining power and signal. The intuitive control panel features rotary encoders for input sensitivity and delay settings.

Constructed from rugged plywood and finished in black lacquer, the KS20 is equipped with three handles per side, an M20 pole mount, and top-mounted rigging points for secure vertical stacking using DRK10/20 frames.

Combining high output, advanced processing, and road-ready durability, the DVA KS20 is a professional-grade subwoofer built to anchor the low-end of any high-performance DVA line array system.
