DB Technologies SUB 615 - 600W 15-inch Powered Bass Reflex Subwoofer with 2.5-inch Voice Coil in Black Finish

The DB Technologies SUB 615 is a powerful 600W 15-inch active bass-reflex subwoofer, designed to deliver exceptional low-end performance in a compact, portable housing. Equipped with a 600W RMS Class-D amplifier featuring SMPS (Switch Mode Power Supply), this subwoofer is capable of generating an impressive 1200W peak power, delivering up to 131 dB of sound pressure level. Despite its relatively compact size and lightweight design, the SUB 615 provides deep, clean, and precise bass reproduction, making it ideal for enhancing the low-end frequencies in various PA systems. Its robust, versatile design allows it to be easily integrated into full-range speaker setups, perfect for live sound reinforcement, mobile DJ events, and fixed installations.

The SUB 615's bass-reflex design enhances low-frequency output, making it capable of filling venues with powerful bass while maintaining a tight, accurate sound. With a frequency response range of 42 Hz to 124 Hz (-10dB), this subwoofer is designed to complement smaller full-range speakers without the need for external processing. It features stereo balanced XLR inputs and outputs, allowing users to connect it in mono or stereo mode, depending on the setup. Users can switch between true bypass and active crossover modes, making it easy to integrate the subwoofer into any existing audio system.

For added flexibility, the SUB 615 includes a polarity inversion switch to optimize phase alignment, and a "Sub Mode" switch that allows users to boost low frequencies when extra punch is needed. The subwoofer's intuitive control panel also provides options for adjusting the subwoofer level and selecting output modes. Its advanced DSP processing (28/56-bit) includes limiters to protect against peak, thermal, and RMS overload, ensuring reliable performance even at high volumes.

Constructed from sturdy plywood with a full metal grille for protection, the SUB 615 is built for both portability and durability. Weighing just 25.5 kg (56.22 lbs), it features side handles for easy transport and handling. The top of the enclosure includes an M20 pole mount, allowing full-range speakers to be stacked on top, creating a complete PA system without the need for additional stands. Its compact footprint and scratch-resistant black finish make it suitable for both portable and permanent installation applications.
