As the larger center channel model in the Reference Series, the RC263 is distinctive for its 3-way design. The heart of this center channel speaker is the 1" (25mm) CMMDa? high-frequency driver mated to our advanced waveguide. This combination provides seamless integration with the midrange and smooth coverage across a wide listening area. A 4" (100mm) flat-piston CMMDa? midrange with a dedicated sub-enclosure provides superior vocal and dialogue intelligibility. Dual 6.5" (165mm) CMMDa? woofers work in conjunction with the sealed enclosure to provide powerful, deep bass response that will make your music and movies come alive. The RC263a??s slender design and elegant details provide a rich appearance that blends well with any d??cor.
