The CM82-EZ-II is an 8”, coaxial, two-way, blindmount, in-ceiling speaker which delivers true high efficiency and performance across the operating bandwidth.

Mounting hardware is included and features a constant-tension fixed-wing mounting system with a 21-gauge “full-metal” steel tile bridge ensuring rapid and secure installation in any sheetrock or drop-tile application. For easy ordering, stocking and installation, this series includes a color-coded (green) tile bridge and optional pre-construction bracket, six-position tap switch for 25, 70.7, and 100 V applications with transformer bypass position.
