for extended lengths. Though the impedance is
low and the likelihood of interference low, this
may help reduce hum and RF interference. When
securing the wire, use care not to staple or nail
the electrical conductors. Doing so could result
in a short that might damage the electronics.
More than two pair of these speakers can
be connected to one amplifier. However, we
suggest that you consult a professional if you are
installing more than two pair.
When connecting your speakers, make sure
proper polarity (phasing) is maintained. Simply
put, this means being sure the same wire which
is hooked to the positive terminal of the amplifier
has its other end hooked to the positive terminal
of the speaker. It is important to check this on
all speakers. If the connections on one of the
speakers are reversed, (out of phase) the quality
of your bass will be seriously impaired.
INSTALLATION
As the diagrams show, the speakers utilizes a
metal mounting ring which, after tightening with
the screws provided, acts as a clamp to hold the
speakers in place.
To aid in speaker performance, a fibrous material, such
as fiberglass or polyester fiber, may be placed behind the
speaker. This may also help to reduce unwanted sound
from being transmitted into adjoining rooms.
Once you determine where you wish the speakers to be
placed, do the following:
Using the paper template provided,
mark the speaker cut-out location
making sure that where you wish
the speakers to be placed will not be
obstructed by a stud or other material
hidden in the wall. Proper use of an
electronic stud-finder is invaluable
for this operation. Using the proper
equipment, cut the appropriate
sized hole in the wall. On drywall,
the cleanest cuts will be made with a
drywall saw.
Install the frame and mounting ring assembly by passing
the black mounting ring through the cut-out as illustrated.
(see figures 1 and 2)
For the 8” speakers, observe that
there is a top and bottom to the frame.
The top and
bottom are identifiable by the spacing between the six
vacant screw holes in the black clamp ring. The more-
closely spaced holes are toward the top. Next, verify that
the speaker frame fits into the cut-out. The white frame
should fit snugly and smoothly in the cut-out hole. If the
hole should have been cut a little too large, the flange on
the frame should cover this.
Once the frame is in place, gently tighten all of the screws
so that the mounting ring is up against the back side of the
wall board.
(see fig. 3)
Avoid over-tightening the screws or
it may later become difficult to install the grille.
If the wire has not yet been run, do so, now that you have
access to the wall’s interior. Once the speaker wire has
been run, pull the end of the wire out of the wall, strip back
a section of the jacket as needed, and then expose ½" of
each conductor. Connect the wire to the terminals on the
back of the speaker assembly, observing polarity (+ & -).
Insert the speaker into the frame and install the six screws.
Tighten the screws starting with the middle pair of screws
followed by the top pair and then the bottom pair.
(see
fig. 4)
Use care not to over-tighten the screws or it may
later become difficult to install the grille. Install the grilles
after testing the operation of the speakers. The grilles are
installed by gently working the edge of the grille into the
frame of the speaker, beginning at one corner and working
one or both directions around to an adjacent or opposite
corner.
