The d&b audiotechnik B6-SUB is a compact, high-performance subwoofer designed to extend the frequency response of d&b xS-Series and xA-Series loudspeakers down to 40 Hz. It features a single 18-inch long-excursion driver in a bass-reflex enclosure, providing impressive low-frequency output from a relatively small footprint. The B6-SUB is ideal for a wide range of applications, from small to medium-sized live events, corporate presentations, and houses of worship, where powerful and controlled bass is required without sacrificing space. Its passive design requires external amplification from d&b D-Series or E-Series amplifiers, ensuring optimal performance and protection.
