SoundTube CM82-EZs-II 8" Coaxial In-Ceiling Shallow Can Speaker
The CM82-EZs-II is an 8-inch, coaxial, two-way, blind-mount, in-ceiling speaker that delivers true high efficiency and performance across the operating bandwidth. By incorporating an 8-inch polypropylene driver with a butyl rubber surround in a sealed drawn steel backcan, this speaker delivers maximum frequency response (82 Hz – 22 kHz, - 10 dB) in an integrated enclosure design.
Mounting hardware is included and features a constant-tension fixed-wing mounting system with a 21-gauge "fullmetal" 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-volt applications with transformer bypass position.- Features
Features
- Engineered for applications with limited plenum space incorporating a SoundTube-specific shallow backcan with an install depth of 3.5"
- One 8" (203 mm) polypropylene woofer with butyl rubber surround and one 1.0" (25.4 mm) silk dome tweeter
- Easy-access six-position tap switch for 25/70.7/100-volt and 16 ohm transformer bypass settings allows for easy ordering, stocking and installation
- Reduced amplification costs and maximum efficiency of 88.0 dB sensitivity, 16 ohm impedance and a sealed enclosure
