Rough-In Frame
EASY TO INSTALL.
The ERS models feature
mounting clamps that
swing out to securely grip
your wall from the inside.
Because they need not be
mounted to a stud, the ERS speakers can be
placed for optimal sonic performance and
installation ease.
ROUGH-INFRAMES.
Optional rough-in frames are available for use
in new-construction installations before drywall
is installed.
THE LATEST EMBODIMENT
OFAPOWERFUL HERITAGE.
CERAMIC METAL MATRIX DIAPHRAGMS.
Ceramic Metal Matrix Diaphragms reveal all the
nuances of today’s music and film recordings by
virtually eliminating unwanted resonances.
The key is a ceramic compound called alumina.
Three times as stiff as titanium – and 85 times
stiffer than felted paper – alumina is deep-
anodized to an aluminum core to create a
three-layer sandwich. CMMD adds bass impact
to each ERS model, and delivers open, detailed
and clean mid and high frequencies.

ERSTM SERIES.
IN-WALL LOUDSPEAKERS.
With the revolutionary, patented Ceramic Metal
Matrix Diaphragm (CMMDTM) technology of Infinity’s
finest bookshelf and floorstanding loudspeakers
and a simplified mounting system. Infinity’s ERS
Series is a compelling choice for exceptional
whole-house and surround sound home theater
applications, and ideal for use with today's plasma,
LCD and DLP television displays.
Infinity’s CMMD transducer cones deliver rich,
resonance-free performance across their entire
frequency range.The result is sonic accuracy
without distortion that delivers all the excitement
of your favorite music and film soundtracks.
With unobtrusive paintable grilles and baffles and
a mounting system that ensures easy installation,
the ERS Series is the in-wall solution that music
and film enthusiasts have been waiting for.
Outstanding performance from speakers that don’t
stand out in a room. ERS from Infinity.
