Model details
A powered subwoofer for extending a portable PA system into the low frequencies. Integrate its level, polarity and filtered outputs with the main speakers for a coordinated full-range system. Its 18-inch driver and 700 W Class H amplifier provide a self-contained low-frequency section without an external power amp. Balanced XLR signal connections suit a mixer or processor feed; position the sub and tops deliberately where their frequency ranges overlap.
Typical uses: Band PA · DJ playback · Portable low-frequency reinforcement
