dB Technologies SUB612

dB Technologies SUB612 – Compact and powerful 12” active subwoofer with 600 W RMS
The dB Technologies SUB612 is a compact yet impressively powerful 12” active subwoofer that delivers up to 129 dB of sound pressure despite its light weight of just 19.8 kg. With an efficient 600 W RMS Class-D amplifier featuring SMPS technology and a precise bass-reflex design, the SUB612 delivers a tight, defined, and powerful low-frequency response—perfect for small and medium-sized PA installations.

Thanks to separate balanced crossover outputs for the left and right speakers, the user can build a complete PA system with just one subwoofer and two tops—without any external processors or crossover filters. The SUB612 also offers stereo/mono selection, a polarity switch, a link mode (True Bypass or X-Over), and a Sub BOOST mode that provides extra low-end punch when needed.

The rugged cabinet, made of black-lacquered plywood, is built to withstand professional touring. The ergonomic top handle and M20 stand mount make transport and setup quick and easy.
