d&b audiotechnik B12 Mobile-specific Small to Medium Format Ground Cardioid Subwoofer

The d&b audiotechnik B12-SUB delivers professional-grade low-frequency performance in a compact, ground-stackable design. Featuring dual long-excursion neodymium drivers, a front-facing 15" bass-reflex unit and rear-facing 10" bandpass driver, this subwoofer produces a cardioid dispersion pattern from a single amplifier channel, minimising rear energy for superior control. With a frequency response of 39 Hz to 150 Hz, it provides tight, impactful bass ideal for mobile and small-to-medium format applications.

The rugged plywood enclosure features a weather-protected 2K finish, reinforced metal grilles, integrated side handles, heavy-duty rear wheels, and stackable runners for secure transport and setup. Perfect for complementing the CCL system with powerful low-end extension.
