The Action 118A is a powered horn-bass subwoofer system designed to provide extended bass response for the Action full-range cabinets. A powerful 3200 Wpeak Class D amplifier drives a D.A.S. 18LX long excursion bass loudspeaker incorporating a 4″ voice coil for high power handling and output. The Action 118A is powered by a Class D amplifier with switch mode power supply (SMPS), digital signal processing (DSP) and a 3200 Wpeak power. The amplifier has a unique EQ switch which allows the user to select a Deep subbass response or a Loud bass response. The system includes two balanced inputs with stereo filtered output connections for 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.
