The Vantec 18A is a powered subwoofer system designed to provide extended bass response for the Vantec full-range cabinets. A 1500 Wpeak advanced Class D amplifier drives a D.A.S. 18LX long excursion loudspeaker incorporates a 4" voice coil for high power handling and output.

The Vantec 18A subwoofer system offers two balanced inputs with stereo filtered output connections for Vantec satellite systems. The variable crossover ranges from 80 Hz-125 Hz and can be defeated to offer stereo "loop thru" connections. A gain control and polarity reverse feature increase user control over the system. A standard 35 mm pole mount socket allows the Vantec 18A to be used with satellite systems.
