The Action 18A is a powered subwoofer system designed to provide extended bass response for the Action full-range cabinets. A 1500 W peak Class D amplifier drives a D.A.S. 18H bass loudspeaker. The 18H loudspeaker incoporates a 4″ voice coil for high power handling and output.
The subwoofer system includes two balanced inputs with stereo filtered output connections for Action satellite systems. The variable crossover ranges from 100 Hz-160 Hz and can be defeated to offer stereo “loop thru” connections. A gain control and polarity reverse feature increase user control over the system.
