Speaker Placement

Location and position are vital to your speaker's performance.  The ideal 
location is on a table or shelf positioned near the corner of a room.  A 
shelf attached to a wooden wall (or some other acoustically hard surface) 
greatly reinforces the speaker's sound quality.  If possible, place the 
front edge of the speaker flush with the front edge of the shelf.  For the 
best sound, avoid floor locations; floor coverings can absorb much of the 
sound.

We recommend that you play a familiar, wide-range recording and experiment 
with speaker placement until you find the location that provides the best 
sound for your needs.

If you are using another speaker with your PRO-X44AV, for the best stereo 
image, the distance between your speakers should be about equal to the 
distance from the main listening area to a point halfway between the 
speakers.

If you must place your speakers farther apart, turn them slightly inward.

You can mount your PRO-X44AV in a wall or under a shelf using optional 
speaker brackets (RadioShack Cat. No. 40-2063).  Or, you can use a 1/4 
inch wall-mount speaker bracket.  Follow the instructions provided with 
the bracket(s).

Note:  When you use the 1/4 inch wall-mount bracket, remove the screw on 
the back panel of the speaker so you can thread the ball shaft.  For any 
other type of mounting bracket, use the mounting holes (indicated by the 
arrows) and leave he screw in place.

Attaching the Rubber Feet

Rubber feet are supplied with your speaker so it will not scratch your 
furniture.  With the thicker feet (marked A) positioned toward the front 
corners of the speaker and the thinner feet (marked B) positioned toward 
the back corners, remove the feet from the paper backing and press each 
onto the bottom of the speaker.

Connections

With the speaker placed at the desired location, measure the distance from 
the speaker to the amplifier.  Use 18-gauge speaker wire for a distance of 
50 feet or less.  For a distance greater than 50 feet, use a heavier 16
gauge wire.

For the maximum bass response and overall best performance, connect eh 
speaker in phase (- to - and + to +).

Speaker wire is either color-coded, with a different color on each side, 
or coded with a ridge or stripe on one side to identify the wire's 
different sides, making the connection process easier.  RadioShack stores 
sell speaker wire to meet most needs.

Follow these steps to prepare the wire and connect the speaker.

1.  Separate the wire conductors for a length of about 2 inches, then
    remove about 1/2 inch of insulation from the wire's ends using a wire
    stripper.

2.  Push down the sparker's black tab to open the negative (-) terminal
    and insert one of the wire's conductors.  Release the tab.

3.  Push down the speaker's red tab to open the positive (+) terminal and
    insert the wire's other conductor.  Release the tab.

4.  Using the speaker wire's coding as a guide, connect the other end of
    the speaker wire to the amplifier's corresponding (right or left)
    speaker terminals.
