The ERS 110DT is a round 2-way, dual voice coil, dual tweeter in-ceiling stereo speaker for use in a wide variety of applications, from stereo and whole-house music systems to complete home theaters. This speaker is perfect for applications where stereo sound is required but there is only space for a single speaker. The ERS 110DT incorporates Infinity''s patented Ceramic Metal Matrix Diaphragm (CMMD™) technology to eliminate unwanted resonances and deliver clear, undistorted sound. The ERS 110DT 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.
