The VANTEC-18A is a powered subwoofer system designed to provide extended bass response for the Vantec-full range cabinets. A 2000 Wpeak advanced Class D amplifier drives a DAS 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.
