REVEL I20/I30 Back Box
Installation Instructions
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.
