dB Technologies SUB615

dB Technologies SUB615 – Powerful and compact 15” active subwoofer with 600 W RMS
The dB Technologies SUB615 is an active 15” bass-reflex subwoofer that combines high performance, a compact design, and impressive sound pressure. With a 600 W RMS Class-D amplifier featuring SMPS technology, the SUB615 delivers up to 131 dB SPL and offers deep, clean, and precise low-frequency reproduction—ideal for both live rigs and mobile PA systems.

The SUB615 makes it easy to build a complete 2.1 system with just one subwoofer and two tops, thanks to balanced X-Over outputs that eliminate the need for external crossovers. You can choose mono or stereo input, enable polarity reversal, and select between True Bypass or X-Over mode. In addition, the Sub Mode switch provides a low-frequency boost when extra punch is needed.

The lightweight yet rugged plywood construction (25.5 kg) features a full-front metal grille and a scratch-resistant black finish. Integrated side handles simplify transport, and the top panel design facilitates stacking multiple subs for larger installations. An M20 stand mount also makes it easy to mount a top speaker directly on top of the subwoofer.
