Where and how you position each
STS-150 speaker has a great effect
on the overall performance of your
sound system.
For the best sound and stereo effect,
place the speakers so the distance
between them is about the same as
the distance between the listening
area and a point halfway between the
speakers.

Cautions:

speaker where it is exposed to
direct sunlight or excessive
humidity.
• Do not place the sp eaker where it
might be knocked over or hit by
falling objects.

If you place the speakers too far apart,
a sound “hole” could occur and you
might not get t he proper st ereo ima ge
in the listening area. Compensate for
this by angling the speakers slightly in
toward the listening area.
If you place the speak ers too close t ogether, you could cancel out the stereo image and the sound might seem
to be monaural. Compensate for this
by angling the speakers slightly away
from the listening area.

For the maximum increase in bass response, place your speakers directly
on the floor and positioned against a
wall or in a corner.
To decrease the bas s response, rai se
your speakers off the floor or move
them away from the wall or corner.
Avoid placing your speakers on a surface that absorbs sound, such as thick
carpeting. We recommend you experiment to find the best setup for your
sound system.
CONNECTIONS
Cautions:
• Take care never to exceed the
speaker’s maximum power rating
(see “Specifications”).
• To avoid any damage to the
speaker or amplifier/receiver, turn
off the amplifier/receiver before
making connections.
• We recommend you use colorcoded or marked wire to help y ou
correctly connect the wire. Some
color-coded wires have a stripe
running down one side of th e conductor’s insulation. S ome marked
wires have ridges along one side
of the conductor’s insulation.
Follow these steps to connect each
speaker to your receiver/amplifier.
1. With the speakers placed in the
selected locations, route the
speaker wire from each speaker
to the receiver/amplifier.
2. Separate the conductors for a
length of about 2 inches on each
end.
3. Strip
1
/2 inch of ins ula tion fro m t he
ends of each conductor, then twist
each end.
