DB Technologies SUB 615 Active Subwoofer
Engineered for touring reliability and impressive punch, the DB Technologies SUB 615 brings stadium-grade bass performance to compact PA rigs. Marrying a high-efficiency 600 W RMS Class-D amplifier with a purpose-built 15-inch transducer, it reproduces low frequencies with surgical precision—hitting a commanding 131 dB SPL while weighing just 25.5 kg.
Power & Precision in One Box
The SUB 615’s SMPS Class-D module unleashes 1200 W peak power, routed through a 28/56-bit DSP that keeps dynamics tight and distortion invisibly low. Peak, thermal and RMS limiters safeguard your investment so you can focus solely on your mix.
Smart Connectivity & Control
Forget external processors—the integrated crossover delivers balanced left/right feeds, selectable for true bypass or 100 Hz high-pass filtering. Moreover, a single switch engages Sub Mode for extra LF weight, while polarity inversion ensures seamless coupling with any top box.
Road-Ready Construction
Crafted from premium plywood and shielded by a full metal grille, the cabinet resists scratches and knocks on the road. Additionally, ergonomic side handles maximise portability, and an M20 pole mount plus stack-friendly top panel simplify building larger arrays.
