ERSTMSERIES.

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.

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 deepanodized 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.

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-IN FRAMES.

Optional rough-in frames are available for use in new-construction installations before drywall is installed.
