PREPARING THE TOWERS
ATTACHING THE PLINTH
Place a soft cloth on the floor to protect the
speaker.
Invert the loudspeaker and place it on the cloth.
Place the plinth on the loudspeaker noting the
orientation.
Align the plinth with the mounting holes in the
base of the speaker.
Attach all four screws firmly to secure the plinth.
ATTACHING THE SPIKES
CAUTION: SPIKES ARE SHARP.
Make sure that there are no wires or hidden
obstacles that could be damaged by the spikes
in the immediate operational area of the
speakers.
NEVER drag a loudspeaker on its spikes. Always
lift it. If the item is heavy get assistance.
A mounting hole is located at each corner of the
plinth. Thread a spike through each hole.
Tighten the collar finger tight so that the spike
is secure but not locked in place.
After all the spikes are attached, invert the
loudspeaker and place it carefully on the floor.
LEVELLING THE TOWERS
Loosen the top collar on each spike one turn.
Place a small spirit level on the plinth.
If the floor is not perfectly level you will find that one spike is off the ground. Starting with this spike, unscrew it so that it touches
the floor. Move the other spikes in and out so the speaker does not wobble and is level front and back and sideways. Now tighten
the top collars to lock the spikes firmly in position

REAR PANEL CONNECTIONS
The WA-8SB and WA-12SB subwoofers use he
same power amplifier. The differences are that
the WA-12SB will produce higher sound levels
with deeper bass reproduction. Connection and
operation of the two units is identical.
PLACEMENT
Although the unit may be placed almost
anywhere in the room, we recommend that is
placed in front of the listener central to the
listening position. There should be a mains
outlet within easy reach.
The bass port is mounted under the subwoofer
firing downward and moves a lot of air at high
volume, so make sure the floor is sound. The
subwoofer is front-firing so do not place it
behind surfaces or objects that may rattle.

operational. If your subwoofer is disconnected from the mains
or the Power switch is “Off”, the indicator will be extinguished.
