PRO-LX5 II Two-Way Die- Cast Speaker

Your PRO-LX5 II Two-Way Die-Cast
Speaker is small in size, but not in
sound! Its 5-inch polypropylene woofer
accurately tracks signals to provide out ­standing bass, while the wide-an gle di­pole tweeter produces crisp, detailed
highs with 360

dispersion.

×

Your speaker’s acousti c design match­es the woofer and tweeter with the en­closure and damping materials to
provide amazingly smooth and broad
frequency response.

Your PRO-LX5 I I can handl e up to 130
watts of power. The speaker is magnet­ically shielded, so you can safely place
it next to your television or monitor.

SPEAKER PLACEMENT

Location and position are vital to your
speaker’s performance. The i deal 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 t he shelf. For the
best sound, avoid floor locations; floor
coverings can absorb much of the
sound.

We recommend t hat you p lay a fam iliar,
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-LX5 II, for the best stereo im­age, the distance betwee n 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-LX5 II on a
wall, under a shelf, or on a cei ling using
optional speaker brackets (RadioShack
Cat. No. 40-2063). Or, you can use a

/8­inch wall-mount speaker bracket. Follow
the instructions provided with the brack­ets.

Note:

When you use

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 the screw
in place.

A TTACHING 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 pap er backing and
press all four feet onto the bottom of the
speaker.

CONNECTIONS

With the speaker placed at t he desired
location, measure t he 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 heavier 16-gauge wire.

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

Speaker wire i s 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, m ak ing the
connection 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
from the wire’s ends using a wire
stripper.

the opening. Then turn the terminal
clockwise to tighten it.

3. Turn the speaker’s positive (+) ter­minal counterclockwise to loosen it
and insert the other wire end into the
opening. Then turn the terminal
clockwise to tighten it.

4. Using the speaker wire’s cod ing as
a guide, connect the other end of
the speaker wire to the amplifier’s
corresponding (+ or –) speak er ter­minals.

REMOVING THE FRONT
GRILLE

If you ever want to remove the front
grille, grasp the edges of the grille and
gently pull it away from the cabinet.
