The OWS-1 is an on-wall speaker designed to complement any Infinity speaker series with CMMD™ or MMD™ drivers, in a variety of applications. Using an ultrathin enclosure that measures only 4-1/2 inch deep, the OWS-1 is ideal for use as a surround channel or as an alternative to in-wall speakers. The OWS-1 incorporates Infinity's proprietary Ceramic Metal Matrix Diaphragm (CMMD™) technology to eliminate unwanted resonances and deliver clear, undistorted sound. Available in a black or white finish, the OWS-1 fits easily into any decor.
