The Avant 118A is a powered rear-loaded horn-bass subwoofer system designed to provide extended bass response for the Avant full-range cabinets.

A 1250 W Class D amplifier drives a D.A.S. 18LX log excursion bass loudspeaker. The 18LX loudspeaker incoporates a 4″ voice coil for high power handling and output.

The Avant 118A incorporates a 1250 W Class D amplifier with switch mode power supply (SMPS) and digital signal processing (DSP).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 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.
