DB Technologies SUB 618 18″ Active Subwoofer
The DB Technologies SUB 618 brings concert-grade low-end to compact PA systems. Harnessing 600 W RMS Class D amplifier and a precision 18 inch transducer, this active subwoofer unleashes thunderous 133 dB SPL. Meanwhile, it retains surgical accuracy down to 35 Hz. The SUB 618 expands your system’s depth without the need for external processors.
Thunderous Low-End in a Compact Footprint
Firstly, the 18 ″ woofer with a 2.5 ″ voice coil is loaded into a bass-reflex enclosure tuned for maximum punch. Moreover, expect room-filling bass that never loses definition, ideal for pairing one sub with two full-range tops for a perfectly balanced stereo rig.
Intelligent Amplification & DSP
The onboard Class D module delivers 600 W RMS (1200 W peak) through a 28/56-bit DSP platform. Furthermore, selectable crossover routing, polarity inversion, and Sub Mode bass boost let you tailor the response on the fly. Meanwhile, peak, thermal and RMS limiters guarantee reliable performance night after night.
Road-Ready Construction & Flexible Deployment
Weighing only 31 kg, the rugged plywood cabinet is finished in a scratch-resistant coating and protected by a full-metal grille. Integrated side handles, an M20 pole mount, and stack-friendly top panel speed up set-up times and ensure safe, tidy arrays.
