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.
A user selectable low pass filter ensures a smooth
transition to top systems.
Configured with an Action 12A or Action 15A the result
is a transportable, high performance sub-satellite system.
The subwoofer system includes two balanced inputs with
stereo 100 Hz filtered output connections for Action
satellite systems. The high pass filter can be defeated to
offer stereo “loop thru” connections. A gain control and
polarity reverse feature increase user control over the
system.
Signal present and limiter leds indicate the system status
and assist in setting the optimum level, via the level
control knob.
The top panel contains a pole mount socket for use with
35 mm metal posts for mounting fullrange D.A.S.
systems above the Action 18A sub-woofer unit.
