High-Linearity Mid-range Cone Transducer
CMCD models include the CMCD-81J, CMCD-81H, and the CMCD-61H. Each CMCD assembly incorporates a JBL cone midrange driver, a 3 slot annular-ring phasing plug, and a thermally conductive rear chamber. An optimal 4-inch exit-diameter and a correct exponential expansion provide excellent coupling to the entire family of Progressive TransitionTM midrange wave guides.
