The main speakers are usually placed in the front of the room, on
either side of the TV or video projector. They should be placed a
minimum of 6 feet apart, and if the furniture placement allows, keep
them at least 12 inches from all walls. To calculate the best placement,
measure the distance between the speakers themselves and the
listening position. Your distance from the speakers should be roughly
1.5 times the distance the speakers are apart from each other. For
example: If the distance between each speaker and the listening
position is 9 feet, then the speakers should be 6 feet apart from one
another. This will provide excellent stereo separation and imaging
for music playback. This is just a starting point, the room's acoustics
and furniture placement will vary the placement of the speaker. Use
your best judgment and experiment with speaker placement. Slight
adjustments can provide significant improvements in performance.

These models can be wall mounted using the keyhole or threaded
insert on the back. The threaded insert is an imperial 1/4-20 (CB-5,
CB-10) or 3/8-16 (CB-20, CC-5) thread and should be compatible with
various aftermarket mounting systems.

When the speaker will be installed on a bookshelf or on a stand,
please attach the 4 rubber bumpers to the bottom of the speaker,
as this will protect both the mounting surface and the speaker
from damage. Simply peel the bumper off its sheet and stick it in
place on the bottom of the speaker, one bumper per corner. The
rubber bumpers also help decouple the speaker from the book-
shelf or stand.
cr-10 (Diagram 6)
The rear speakers can vary greatly in position depending on the
room layout, and the furniture placement. The ideal position is either
on the side walls, or rear walls.
Side Wall: This position utilizes the ceiling or rear walls of the room
to reflect sound and create the "surround" effect.
rear Wall: This is generally used when the side wall position is not
available to you, due to furniture placement or room dimensions. It is
also used in a 6.1 or 7.1 surround configuration.
Both mounting positions have their advantages and disadvantages,
the position offering the best coverage of the entire room should be
chosen. The goal of the surround speakers during movie reproduction
is to create an "atmosphere" around you. The rear channel speakers
are ideally placed an equal distance from you as compared to the front
speakers. But this is not always possible in a home environment. The
CR-10 will emit sound from both sides of the speaker, and is best
placed where it can use the ceiling and walls to reflect the sound
around the listeners. The best mounting position for a 5.1 system is
the Side Wall position, as it makes use of the rooms' ceiling, rear walls,
and side walls. It will create a lifelike surround effect and make the
room sound larger than it is. In this position, try to mount the speaker
so that it is beside you or slightly behind you. The height should be
above ear level, at approximately 2/3 of the height of the wall. 6 feet off
of the ground is typically a good starting point, and the speaker should
be 2 feet above your head when seated. These general guidelines
should aid in positioning choices.
You can also achieve excellent results in the rear position. Try not
to place the speakers directly into a corner. Leave 2 or more feet
between the edge of the cabinet and the side wall, so the sound can
reflect into the room environment. The rear position is usually chosen
when your room will not accommodate the side wall position due to
unequal walls, a doorway, or a large opening, etc. Whether you use 2, 3
or 4 surround speakers, it is recommended that all surround speakers
are at the same height.

NOTE: The CR-10 features a very simple wall mounting system. Careful
attention must be made to mount it securely as the speaker is heavy
and damage to the product and/or injury could result from improper
mounting. Please follow the directions carefully!
1) Select the mounting position best suited for your room.
2) Place the speaker vertically against the wall in the desired
mounting location and push firmly on the speaker cabinet to
mark the wall. (Diagram 7a) This is where you need to insert the
appropriate mounting hardware to securely fasten the speaker.
Hardware is not included with the speaker, as building materials
vary greatly in different countries, but the recommended screw
head size is a #8. Screw length is to be determined by the wall
material.
3) If you are mounting directly to drywall, please ensure that you
use the appropriate anchors, as screws into drywall itself will not
provide a secure mount. Insert the anchors AND screws until tight.
Try to locate into wall studs wherever possible. (Diagram 7b)
4) Hold the speaker vertically and insert the screw head into the
large hole. (Diagram 7c) Let the speaker slide down into place.

BI-poLe/DI-poLe SWItcH – cr-10
The Bi-pole/Di-pole Switch allows you to change the type of sound
field the speaker will produce. Note: Regardless of the switches'
position, the two tweeters will continue functioning.
1) In the "Bi-pole" position the two tweeters are engaged and are
operating in phase with each other. The resulting sound field is
expansive, and with correct placement, the sound will reflect off
of room boundaries to create a large sounding surround field.
2) In the "Di-pole" position the tweeters are active, but are wired
out of phase from each other. The resulting sound field is even
more expansive, and can create an even larger effect than the
bi-pole mode.

Note: Always experiment with the controls, and adjust them to your liking.
The chart will give you a good starting point, but each room is different, and
depending on the CR-10's location, furniture placement and materials in the
room, adjustments may be necessary.
