Infinity Reference RC252 | Black 2-way Center Speaker The RC252's slender profile allows for flexible placement within your entertainment system. It is sonically matched to companion Reference Series floorstanding, bookshelf and surround loudspeakers and powered subwoofers allowing you to create the ideal system solution for your needs. The combination of the acoustical science and patented designs found in the 1" (25mm) CMMD (Ceramic Metal Matrix Diaphragm) tweeter and advanced waveguide provides seamless sonic integration with the CMMD woofers while providing excellent highfrequency detail and smooth coverage across a wide listening area. Powerful bass is key to a highquality sound experience and the strength of Infinity's extremely rigid woofer cones  constructed from CMMD (Ceramic Metal Matrix Diaphragm)  help to deliver a wide frequency range with minimal distortion. These woofers work in conjunction with the sealed enclosure to provide superior vocal and dialogue intelligibility and powerful deep bass that makes your music and movies come alive. Infinity's advanced acoustical modeling design places the drivers in the ideal location within the cabinet allowing them to work with the enclosure and not against it. The advanced positioning and crossover network integration reduce harmful sonic artifacts that would otherwise detract from the overall performance of the loudspeaker. The slim profile of the RC252 is complemented with a rich, black woodgrain finish and hidden fasteners that provide for a clean look that blends easily with any dcor.
