For more bass, place the speakers between 18 and 36 inches
from an adjacent wall as measured to the center of the speaker.
Avoid placing the speakers less then 18 inches from an adjacent
wall. When placing speakers near a corner, avoid locating them an
equal distance from the two adjacent srfaces.
When used in a home theater the front left and right speakers
should be separated from each other a distance of 0.8 to 1.2
times the seating distance (assuming they are on the same
plane as the center speaker). For example, if the seating position
is 10 feet from the viewing screen and/or center speaker then
ideally the distance between the left and right speakers should
be somewhere between 8 and 12 feet, (10 x 1.2ft = 12ft). If the
speakers are located behind an acoustically transparent screen
then all the speakers should be oriented portrait style. The
tweeter should be aimed toward the listening area.
WIRING
To achieve maximum performance we recommend that the
speaker cable be at least 16 gauge or larger for runs over 50 feet
(15m) and that the cable be double insulated. A CL-2 or CL-3 rated
cable may be required. Check local codes. “Zip cord,” which is
single insulated and is often made with clear insulation, should be
avoided as it is not as durable. Allow about 2½ feet (0.8m) of free
cable at the speaker cut-out and sufficient length at the other end
to reach the electronics. Having to add extra cable later can be
tedious and time consuming.
Avoid bundling speaker cables parallel to electrical cables 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 cable, use care not to staple or nail through the
electrical conductors. Doing so could result in a short that might
damage the electronics.
When connecting your speakers, make sure proper polarity
(phasing) is maintained. Simply put, this means ensuring the
same wire which is connected to the positive terminal of the
amplifier has its other end connected 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 sound quality will be impaired.
INSTALLATION
If the drywall has not yet been installed a Rough-in-Bracket (RIB-
LCR) may be used to reserve the speaker location on the wall.
The RIB-LCR brackets are available from the distributor or dealer
where the speakers were purchased. When these brackets are
used the holes are cut when the drywall is installed. The cable can
be tied off on the bracket after securing the cable to a nearby joist.
If the drywall is installed and the speaker locations have not yet
been established, then do so now. Assess the wall for possible
concealed obstructions such as wiring, plumbing, etc. Inspect the
backside of the wall, the attic, and/or the crawl space if available
for clues to possible obstructions. Use inspection holes with
inspection tools (camera, mirror, flashlight, etc.) if absolutely
necessary. Use a “stud finder” to locate the positions of the studs.
The k-W6LCRSd is shipped with a
Clamp Ring for clamping the speaker
to the wall. The edge of the speaker
opening must be at least 1/2" (13mm)
away from a stud if the speaker is
installed in the portrait orientation.
Once the speaker locations are
established use the cardboard template
(the outside of the inner cardboard
rectangle) to mark the speaker cut-
out. The dimensions for the cut-out
are listed in the chart on the previous
page. Using the proper tool, cut the
appropriate sized hole in the wall. On
drywall, clean cuts can be made with a
drywall saw.
If the cable has not yet been run, do so
now that you have access to the wall’s
interior.
To aid in speaker performance, a fibrous
material, such as fiberglass, may be
placed behind the speaker. This may
also help to reduce unwanted sound
from being transmitted into adjoining
rooms. If the wall space has blown or
loose insulation, care must be taken
to prevent the loose insulation from
entering the back of the speaker. This
can be accomplished by placing a batt
of fiberglass insulation over the back
of the speaker.
Install the frame and retro ring
assembly by passing the metal retro
ring through the cut-out as illustrated
in
figures 1 & 2 to the right.
The
frame should fit cleanly, without
interference, in the cut-out hole. If the
hole is a little small then trim the hole
as needed. Lightly tighten the screws
to secure the retro ring against the back
of the wall
(see fig. 3).
Use care not to
over-tighten the screws or the frame
may become distorted.
Note: use only
the 4 outer holes for mounting the
frame.
Pull the end of the cable out of the wall,
strip back a section of the jacket as
needed, and then expose ½" (13mm) 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 eight screws
(see fig. 4).
SOME OF THE WAyS THIS SPEAkER CAN BE uSED
This speaker can be used for 2-channel High Resolution audio or
for nearly any speaker location within a home theater system. The
chart to the right provides suggested tweeter orientations for a
number of common speaker locations within a home theater. We
encourage you to experiment with the tweeter orientation to see
what works best within your system, especially with surround
placements.
While it may seem unconventional to use this speaker in the
Landscape orientation for the center dialog speaker, it is actually
well suited because of the excellent phase coherency between
the tweeter and woofer. The speaker actually outperforms most of
MTM (Mid-Tweeter-Mid) designs that have become commonplace
for the center dialog channel.
ROTATING THE TWEETER
•
The tweeter should be rotated into the desired position for
optimal performance.
•
There are detents every 15 degrees. The tweeter will lock into
these detents when positioned over them.
•
Press firmly at the edge of the tweeter waveguide using 4 fingers.
•
A gap of about 2mm will appear at the edge when depressed.
•
Rotate the tweeter into the desired position, releasing when you
feel a detent.
•
NOTE: It may be necessary to moisten one's fingers to achieve
good traction on the waveguide.
•
The detents will not be felt when the waveguide is fully
depressed. Decrease pressure to locate the detents.
LOCkING THE TWEETER INTO PLACE
SPEAkER PLACEMENT
Placement of In-wall speakers should be carefully considered.
Please contact a professional for assistance if you are
uncomfortable with the planning or installation process.
Ideally, the speakers should be located where they will provide
the best possible sound and ease of installation. It is beyond the
scope of this publication to discuss all of the various aspects of
speaker placement but here are some helpful suggestions.
Optional Security Hole
Two holes have been
provided to lock the
tweeter into place and
prevent rotation.
Should it be desirable to
lock the tweeter, install
two #6x3/8
"
(3.5mm
X 10mm) sheet metal
screws with flat washers
in the provided holes.
