Introduction
BreakInPeriod
Congratulations on your purchase of RBH Sound in-wall speakers! Your speakers are the
result of many years of research and development dedicated to producing high quality
products for home audio and audio/video systems.
This manual is designed to give you, the installer or owner, basic information as to the
speaker’s installation and operation. We recommend you thoroughly read through the
material contained in this manual before installing your speakers. This will ensure that
you have an understanding of how to setup your speakers for optimum performance
and allow for years of listening enjoyment.
Allow several hours of listening time to adequately break in the speakers. As the
speakers break-in, the driver suspension will loosen. The result of break-in will be an
increase in low frequency response, improved definition, clarity and detail.
Features
All RBH Sound in-wall speakers feature a swing out dog leg mounting system with
pre-started screws for fast and easy installation. Most RBH Sound in-wall speakers
feature directional swivel tweeters to direct the sound to the main listening area.
All RBH Sound in-wall speakers feature polyswitch protection circuitry designed
to protect the tweeter from being over driven. This circuit will automatically
reset itself once the volume is turned down or the problem causing the circuit to
activate is removed.
Steep acoustic slope crossovers are used to integrate the drivers. The use of
steep crossover slopes allows high power handling, minimized driver interaction
anomalies, and maximizes the clarity with which each driver is able to produce its
respective frequency band.

PaintingtheSpeakers
A paint shield is included with your speakers. This shield can be used to protect the
speaker when painting the speaker’s rim (frame). If you plan to paint your speakers,
we recommend it be done prior to installation. If you decide to paint your speakers
sometime in the future, it is best to remove them from the ceiling or wall. When
painting speakers, the paint shield provided in the packaging must be installed in
place of the grille. The grille can also be painted. Painting the speaker’s grille should
be done with a paint sprayer set to fine. Remove the grille from the speaker, peel off
the grille fabric on the back of the grilles and set aside. Place the grilles on a flat
surface. Do not use a brush or roller on the grilles as this will clog the holes, greatly
reducing the sound quality of the speakers. Do not paint the grilles while attached to
the speakers. Be sure to remove the paint shields from the speakers and replace the
fabric to the back of the grilles before reinstalling them and using the speakers.

RoomSetupSuggestions
With nearly endless placement options, careful consideration for placement of the
in-wall speakers needs to be considered, as installation requires cutting a hole in
your wall or ceiling! When using speakers in home theater applications follow the
guidelines illustrated below.
Swivel Tweeter Placement
The swivel tweeter allows sound to be directed toward or away from the listening
area depending on the application. A tweeter aimed toward your listening position
improves imaging and detail. When using a speaker with a swivel tweeter as front/
main home theater speakers or as stereo speakers in a distributed audio system, aim
the tweeter toward the main listening position. For rear/surround speakers, aim the
tweeter toward the nearest reflecting surface (an adjacent wall or ceiling) for a more
diffuse sound field (for more direct sound, aim the tweeter at your listening position).

RBH Sound in-wall speakers are designed on an infinite baffle configuration. This
means a back can is not required for the speaker to perform properly. However, using
an RBH Sound back can will most likely improve the tightness and control the bass
response. RBH Sound in-wall speakers have also been designed to make installation as
easy as possible. Upon opening the speaker boxes you will notice that the screws are
pre-started into the dog legs or a pinch ring. The basic idea behind in-wall speakers
is the speaker is held in place by sandwiching the speaker and the drywall. A frame
around the speaker conceals the cutout in the drywall and presses against the front of
the wall. Behind the wall, the speaker has a set of dog legs or a pinch ring which cinch
the speaker to the drywall.
CAUTION: Be certain there are no electrical wires, water pipes, heating ducts or any
other obstructions in the planned area of installation before starting to drill or cut
into the ceiling or wall. If there is an electrical outlet nearby, turn off the circuit
breaker to avoid possible injury.
Installing WITH a New Construction Bracket:
If using a new construction bracket cutting the drywall should not be necessary
continue with “Connecting the Speaker” instructions on the next page.
Installing WITHOUT a New Construction Bracket:
Use the cutout template supplied with the speaker for
guidance in cutting the drywall, following “Using the
Template” instructions below.
Using the Template:
1. These speakers are designed to be mounted between
the framing members. Use a stud finder to locate
the position of studs. Make sure you have a 2-inch
clearance from the outside of the cutout hole from
studs.
2. Drill a 1/4-inch hole in the center of the area you
plan to mount the speaker. Cut or bend a piece of
wire (a coat hanger works well) to a 90-degree angle.
Insert the wire into the pilot hole and fish around to
make sure there aren’t any obstructions which will
interfere with the installation.
NOTE: If you must choose another location, the pilot
hole can be easily patched.
3. Once a suitable location is found, use masking tape to
temporarily place the supplied cutout template on the
wall, centered over the pilot hole. Draw a circle around
the inside edge of the template.
4. Carefully cut the hole with the appropriate cutting tool to remove the material

inside the circle inscribed by the template.

SpeakerInstallation(continued)
NOTE: The frame will overlap the cutting edge by about a 1/4-inch which will
mask any minor cutting inaccuracies.
5. Confirm the speaker easily fits into the hole, without any gaps.
Connecting the Speaker:
6. Pull the speaker wire out of the hole and connect
the speaker. Split the two conductors of the
speaker wire apart about 3-inches so they form a
“Y”. Using wire strippers, remove about 1/2-inch of
insulation from each of the two conductors of the
wire to expose the bare metal and twist each of the
conductors into a single unfrayed strand.
The speaker terminals will accommodate any
speaker wire up to 14-gauge. Select an appropriate
wire gauge from the following chart:
18 gauge for up to 50-feet
16 gauge for up to 100-feet
14 gauge for up to 200-feet
NOTE: When connecting a speaker it is very
important to retain the correct polarity (improper
polarity will cause reduced bass performance and unnatural imaging effects).
To do this, be sure the wire attached to the positive terminal on the speaker
(marked [+] or colored red) connects to the positive terminal on the amplifier.
Similarly, the negative terminal (marked [-] or colored black) must connect to
the negative terminal on the amplifier.
Finishing the Installation
7. Slide the speaker into the pre-cut hole in drywall or new construction bracket
keeping the speaker cable above and out of the way to prevent pinching it.
8. Tighten the screws. The dog legs will automatically swing out and tighten
(pinch) themselves against the new construction bracket or the drywall with
the turning of the screws and will hold the speaker solidly in place. Don’t over
tighten screws, if you over-tighten the screws the speaker frame may bend which
will make it difficult to properly install the grille.
NOTE: If using a drill/driver, set the clutch to a low setting to prevent over
tightening and possible damage to the frame or dog legs. If using hand tools,
tighten just until firm.
9. If the speaker has any tone controls or has a pivoting tweeter, leave the grille off
until you can listen to the speaker. Once the speaker is adjusted, install the grille.
NOTE: Handle the grille carefully, as they pressure-fit into the installed speaker.
If the grille does not install easily try loosening the mounting screws before
resorting to forcing the grille into the speaker.

Rear Enclosure
The rear enclosure is a rectangular pre-
construction box for in-wall speakers. The
BB-S can be mounted in-between standard
2x4 stud-frame construction and enhances
the sound quality of in-wall speakers. It also
prevents the sound from being transferred
into rooms on the other side of the wall.
Blank Plates
Blank plates are a very clean and efficient
way to cover the holes left in drywall when
a new construction bracket is used or a
speaker is removed. Install blank plates when
in-wall speakers will not be immediately
installed after drywall is finished.
New Construction Brackets
An excellent way to guarantee placement of
in-wall and in-ceiling speakers prior to drywall
installation, New Construction Brackets (NCB’s)
also make installation of in-wall speakers faster
and easier by reducing time and mess. Once
drywall is installed, just connect the speaker to
the speaker wire and install. New Construction
Brackets eliminate the time and need to locate
and cut drywall before speaker installation.
