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:
• To prevent the cabinet from wa rp­ing or discoloring, do not place the 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.
