IMPORTANT SAFETY INSTRUCTIONS
Read Before Starting Installation
WARNING This enclosure is not listed for use in air handling plenums. Installation
of this enclosure in walls or ceilings of fire barrier rated construction
require that construction methods shall be employed in order to comply
with local building or life safety codes. Consult your local Authority
Having Jurisdiction (Building, Electrical, or Fire Safety Inspector) to
determine what acceptable construction methods will be required.
WARNING The I20 Inwall Back Box weighs 19 lbs. (8.6kg) empty, and weighs 32
lbs. (14.52kg) with an I20 speaker system installed in it. The I30 Inwall
Back Box weighs 19 lbs. (8.6kg) empty, and weighs 36 lbs. (16.3kg) with
an I30 speaker system installed in it.
ANSI/EIA 636 Recommended Loudspeaker Safety Practices, Section 16.3
recommends that the mounting system used to install the Inwall Back
Box in walls or ceilings should support the weight of the product plus at
least four times the weight of the product being installed. That means,
for an I30 installed in an Inwall Back Box, the mounting system should
be able to support at least 180 lbs. (82kg).
It is strongly recommended that the installer consult a construction pro-
fessional or a professional engineer to determine the appropriate
mounting methods to be used for each specific installation location.

About the Back Box
Thank you for purchasing the Revel
I20/I30 Back Box, an optional rear enclo-
sure for the Revel I20/I30 In-Wall
Loudspeaker which provides optimum vol-
ume for woofer alignment and reduces
acoustic bleed through to rooms adjacent
to your listening area. The I20/I30 Back
Box also functions as a mounting bracket
designed to facilitate the installation of the
Revel I20/I30 In-Wall loudspeakers in new
construction or major retro-fit installations.
The back box improves sonic performance
while providing solid support for the
speaker mounting frame and baffle assem-
bly. Since the back box is installed before
the drywall is mounted, it allows the
speakers to be mounted in a clean, effi-
cient manner.
The Revel I20/I30 Back Box measures
17.50 x 29.50-inches (444.5 x 749.3mm)
(including the flanges). The back box is
designed to mount between two 2x4-inch
(or 2x6-inch) wall studs on 16-inch centers.
See the illustrations below for inner dimen-
sions.

lation:

age caused by improper installation.

Installation Instructions
Note
Figure 3 (above) shows the depth of the
back box. It can be installed in walls con-
structed with standard 2x4s. It is impor-
tant to note that the speaker mounting
frame requires a minimum depth (from
the wall face to the inside back of the
I20/I30 Back Box) of 3-1/2 inches
(88.9mm) for proper installation. This can
only be achieved by using 5/8 inch
(15.9mm) sheetrock on the wall face. It is
recommended the installer consult with
the sheetrock installer before beginning
the installation.
Caution
Installers are advised to wear work
gloves and face mask when installing
the back box and making wire connec-
tions, as the back box contains fiber-
glass.
To install the back box:
1. Use a tape measure to determine the
location where the speaker is to be
mounted. Refer to the Revel I20/I30
In-Wall Loudspeaker Owner’s Manual
for speaker placement considerations.
Record exact measurements from the
floor, ceiling and an adjacent dry wall
section.
Note
The I20/I30 Back Box eliminates sensitivi-
ty to placement considerations due to
standing waves within the wall cavity as
described in the Revel I20/I30 In-wall
Loudspeaker Owner’s Manual.
2. Position the back box between two wall
studs and into the wall cavity as shown
in Figure 4 (above). The back box must
be placed between standard 16-inch
on-center stud spacing. If desired, the
back box can be mounted upside-down
if you will be mounting the speaker
close to the ceiling.

codes to ensure a proper installation.
Harman Specialty Group is not respon-
sible for any possible damages caused
by improper installation.

the outside of the back box terminal
cup as shown in Figure 6 (next
column). Loosen the terminal connec-
tors by hand (counterclockwise) on the
terminal cup’s positive (+) and nega-
tive (-) binding posts.

codes. Harman Specialty Group is not
responsible for any damages or injuries
that may result from faulty wiring.

6. Place the section of drywall over the
back box.With tape measure and pen-
cil, carefully measure and mark where
to position the wall template (included
with the loudspeaker) by using the
measurements recorded in Step 1.
7. Use the wall template to trace where to
cut the drywall.
8. Cut a small hole in the center of the
template area to make sure the
template is in the right location.
9. After confirming the correct location,
cut the template hole opening as
shown in Figure 6 (below). Use a
carpenter’s level to ensure the opening
is level.
10. Fasten the drywall to the wall studs
using drywall screws.
11. Install the speaker mounting frame
into the wall opening. Refer to the
Revel I20/I30 In-Wall Loudspeaker
Owner’s Manual for complete instruc-
tions.
12. The back box’s banana plugs are locat-
ed inside the terminal cup as shown in
illustration A in Figure 7 (above).
Route wires from terminal cup behind
the speaker frame clamps (to prevent
close proximity with the woofer basket)
until they emerge at the top of the
speaker frame as shown in Figure 8
(below). The banana plugs must be
positioned correctly for a proper
connection. Be sure to avoid contact
with the speaker cone.

as shown in illustration A of Figure 9
above. From the top of the speaker, run

loudspeaker’s binding posts as shown
in illustrations B and C above. The
wires are 18-inches long. If necessary,
use the extra service wire (provided).
14. Loosen the terminal connectors by
hand (counterclockwise) on the bind-
ing posts until the holes in their
threaded posts are visible. Insert the
banana plugs from the top as shown
in illustration B in Figure 9 above.
Make all connections observing the proper
polarity, positive to positive (+) and nega-
tive to negative (-). The banana plugs and
terminal connectors are color-coded for
simple identification: red (positive) and
black (negative).
15. Retighten the terminal connectors to
ensure a secure connection.
16. Refer to the Revel I20/I30 In-Wall
Loudspeaker Owner’s Manual for
complete instructions on installing the
speaker baffle to complete the installa-
tion.
