After reviewing the manual and unpacking your PS-12 subwoofer, we suggest that the four rubber feet be installed
on the bottom of the enclosure to protect the subwoofer and your floor or cabinetry from damage during
installation and setup. These feet can be replaced by the spikes, or removed if desired, after the final location is
determined. Here are some guidelines for using the feet.
DO NOT try to slide your subwoofer with the feet installed. This will damage the foot supports or the feet.
If the PS-12 is placed on carpet, the spikes are likely the best choice since they will penetrate the carpet
and provide a solid and stable footing for the subwoofer.
If the unit is placed on a hard surface then the rubber feet should be used.
You may elect to use only three feet especially if the surface on which you are placing the subwoofer is
uneven, such as a stone or tile floor. See diagram for details.
To install the feet:
Thread the knurled jam nuts onto the desired feet and then screw the feet into the appropriate holes on the
bottom of the PS-12 enclosure. Begin with the feet screwed all the way into the enclosure. Rotate the enclosure
into its upright position and lower the appropriate feet to level the subwoofer and prevent it from rocking. Finger
tighten the knurled jam nuts against the bottom of the enclosure to secure the feet and prevent them from
moving. Use care not to over-tighten the knurled jam nuts as they will be difficult to loosen.

The PS-12 subwoofer was designed for exceptional performance and value. It features a 12" extra-long
excursion woofer with high Bl motor. The bass reflex enclosure ensures extended bass response and high
acoustic efficiency.
The woofer is driven with an integral 300W class A/B amplifier utilizing the patented BASH technology for high
electrical efficiency.
The integral rear-mounted 300 watt amplifier includes several essential controls to contour the subwoofer's
output to blend with virtually all loudspeakers and room environments. These controls, their operation, and
their adjustment are described in a later section of this manual.
An integral low pass crossover network is continuously-variable from 40Hz to 120Hz and can be bypassed if it is
preferable to use an external crossover located in an outboard receiver or processor.
The PS-12's integral amplifier incorporates a defeatable signal-sensing circuit that automatically powers up the
amplifier when a signal is detected.
A double-insulated isolated-ground electrical supply prevents electrical ground loops and reduces the noise floor
of the entire audio system.
The PS-12 is shipped with 8 adjustable feet, (4 spiked and 4 rubber) with tool-less knurled jam nuts. These
feet can be installed in the bottom of the enclosure in either a three-point triangular pattern or more traditional
4 point square pattern. The bottom of the enclosure has 5 threaded inserts arranged to accept either pattern.
