PRO LX7 Bookshelf Speaker
Cat. No. 40-4063
produces high sound quality with very
low distortion, and actually delivers decreasing distortion as the sound
moves to the higher frequency ranges.
Its features include:

internal elements were exclusively designed to maintain shape through all
phases of operation, mo ve diaphragm
elements with efficient speed, and
faithfully reproduce high frequencies.
The 7-inch driver is specially designed
to accurately produce all sonic information from 45 Hz to 2 kHz. The pliable diaphragm in the 3-inch

¥
driver can accurately produce sonic information from 2 kHz to 25 kHz with
extraordinarily low distortion. The
tweeter’s unique design means there
is virtua lly no physica l limitation t o its
production of high-frequency sound.
The speaker cabinet is finished in
black woodgrain vinyl. The black cloth
grille is acoustically transparent, and
you can remove it for safe and easy
cleaning.

SPEAKER PLACEMENT
For the best stereo image, place a pair
of speakers so t he distance between
them is about the same as the distance
between the listening area and the
point halfway between the speakers.
If you must place the speak ers farther
apart, turn them slightly inward. If you
must place them closer to each other,
turn them slightly outward. Experiment
with your speakers’ placement to discover the best location for them.

CONNECTIONS
With a pair of speakers placed in their
approximate locations, measure the
distance from each speaker to your receiver/amplifier.
Use 18-gauge speaker wire for distances of 50 feet or less. For distances
greater than 50 feet, use heavier 16gauge wire.
Note:
For maximum bass response
and the best overall performance, connect your speakers’ terminals to the
corresponding terminals on the receiver/amplifier (+ to +, and – to –). You
can easily make the proper connections with coded speaker wire, available at your local Radio Shack store.
1. Separate the wire’s two conductors at both ends for a length of
about 4 inches.
2. Strip the insulation from the ends
of each conductor to expose
inch of metal wire, then twist the
loose wire strands.

3. Turn the left speaker’s negative (-)
terminal counterclockwise to
loosen it and insert one of the wire
ends into the opening. Then turn
the terminal clockwise to tighten it.
4. Turn the left speaker’s positive (+)
terminal counterclockwise to
loosen it and insert one of the wire
ends into the opening. Then turn
the terminal clockwise to tighten it.
5. Using the speaker wire’s code as
a guide, connect the wire from the
left speaker’s negative (–) termi-

nal to the receiver/amplifier’s left
negative (–) terminal.
Then connect the wire from the
left speaker’s positive (+) terminal
to the receiver / amplifier’s left positive (+) terminal.
6. Repeat Steps 1-5 to connect the
right speaker to the receiver/
amplifier’s right terminals.
