Db Technologies Sub 615 Collection Only B

dB Technologies SUB 615 Active Subwoofer – 600W RMS – Grade B (Unboxed)

The dB Technologies SUB 615 is a powerful, bass-reflex active subwoofer designed to deliver professional low-end reinforcement in a remarkably compact and portable form factor. Equipped with a high-performance 15-inch transducer and a 600W RMS Class-D amplifier, the SUB 615 produces an impressive maximum sound pressure level of 131 dB. This unit is engineered to provide precise, punchy bass that serves as the perfect foundation for mobile DJs, live bands, and permanent small-to-medium venue installations.

The rear panel features advanced DSP processing, allowing for seamless integration into any PA setup. With dual balanced XLR inputs and outputs, you can easily create a 2.1 system by utilizing the built-in digital crossover to feed your full-range top speakers. The interface includes a polarity inversion switch and a Sub Mode button, which activates a low-frequency boost for extra "punch" when needed. Housed in a durable plywood cabinet with a scratch-resistant black coating and an M20 pole mount, the SUB 615 is built for the rigors of the road while remaining light enough for a one-person lift.
