install the speaker, first rotate the dogs
inward. Insert the speaker into the
cutout and tighten the dogs by turning
the screws clockwise. DO NOT OVER-
TIGHTEN THESE SCREWS. Over-tight-
ening the clamps may make the grille
difficult to install. 

(See Figure 17)

.

NOTE: The screws will be easier to turn if
you “prime” them first. Before installing each
speaker, turn the screws in and then turn
them back out to their original positions.

8. Direct the Tweeter. The tweeter is

directed by gently pushing on the edge
of the tweeter grille. It will move 20° in
any direction. For critical listening point
the tweeter to the user’s favorite listen-
ing position minimizing reflections from
the side walls. For surround sound or
low volume background listening cre-
ate more reflections and thus more
ambience by directing the tweeter
towards the side walls. See Speaker
Placement on Page 6.

9. Setting the Bass and Treble cut switch-

es. Listen to a well-recorded piece of
music at the user’s favorite listening
position. a) Listen for bass boominess,
particularly when the speaker is placed
near a corner. Use the -2dB Bass cut to
correct. b) Listen for treble harshness or
ringing, particularly when the speakers are

placed in a room without carpet/ Use the
-2dB Treble cut switch to correct.

10.Install the grille into the speaker. The

grilles should fit snugly. If you have diffi-
culty fitting them in, try loosening the
mounting dog screws (excessive tighten-
ing can distort the shape of the frame
holding the grille in place).

Painting the Speakers

All models may be painted. The plastic
will readily accept most paints.

The speakers must be masked prior to
painting them. The inside circular portion
of the hole template can be used as a
paint mask. Remove the outside portion of
the template by gently pulling along the
perforation. Affix the mask to the front of
the speaker using a piece of tape. Fold the
tape onto itself to form a double-sided
loop. Affix the tape to the tweeter and
place the mask onto the speaker.

The grilles should be painted before they
are installed. For all models, the best
results will be obtained by using a spray
gun or airless sprayer, thinning the paint
(prevents clogging of the grille holes), and
by applying several light coats instead of
one heavy one.

Speaker Phase

Speaker wire has two conductors. One con-
ductor is attached to the negative (-) terminals
and one conductor is attached to the positive
(+) terminals of both your speaker and your
amplifier. Usually, the wire is marked for your
convenience. There are different ways wires
are marked: a stripe on one wire, a ribbed area
of one conductor you can only feel, different
colors of metal wire on each conductor, or
there might be a fabric strand or string wound
into one of the conductors. Of course, there
are some wires which appear completely
identical. Be careful, or you might make a mis-
take.
