The ERS 310 is a round 2-way in-ceiling speaker for use in a wide variety of applications, from stereo and whole-house music systems to complete home theaters. The ERS 310 incorporates Infinity's patented Ceramic Metal Matrix Diaphragm (CMMD;) technology to eliminate unwanted resonances and deliver clear, undistorted sound. The ERS 310 also incorporates a proprietary waveguide design to ensure smooth distribution of sound throughout the listening area. The white grilles and frames are paintable and allow the speakers to blend into any decor.

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