Active Subwoofer dB Technologies SUB 615

The dB Technologies SUB 615 is a versatile active subwoofer designed for professional mobile and installation solutions. Equipped with a 15-inch driver with a 2.5-inch voice coil, this sub provides powerful low-frequency output in the 42–124 Hz range with a maximum sound pressure level of up to 131 dB. With its compact yet sturdy wooden enclosure with a durable finish, the SUB 615 combines high performance with convenient mobility.

A Class D amplifier (600 W RMS, 1200 W peak power) with a switching power supply (SMPS) ensures stable operation even in challenging power conditions. The built-in DSP (28/56 bits) with multi-level limiting (Peak, RMS, Thermal) ensures safe operation and clear, controlled sound.

The SUB 615 allows for flexible system configuration thanks to switches on the amplifier panel: choice between mono/stereo input signal, polarity inversion, Sub Mode for bass boost, and choice between direct output (True Bypass) or built-in crossover (Xover). This allows you to build simple and effective stereo pairs with two satellites without additional signal processing.

The subwoofer enclosure is equipped with a full-size metal grille, M20 threading for mounting satellites on a pole, and handles on the sides for easy transport. The top has a special profile for reliable stacking of several subwoofers in larger systems.
