The SoundTube CM82-EZs-FS 8" Coaxial In-Ceiling Fire Signaling Shallow Backcan Speaker incorporates an 8-inch polypropylene driver with a butyl rubber surround in a sealed drawn steel backcan, which allows this speaker to deliver maximum frequency response (82 Hz – 22 kHz, - 10 dB) in an integrated enclosure design.
Mounting hardware is included for the CM82-EZs-FS Speaker, which features a constant-tension fixed-wing mounting system with a 21-gauge “full-metal” steel tile bridge ensuring rapid and secure installation in any sheet rock or drop-tile application. For easy installation, this series includes a color-coded (green) tile bridge and optional pre-construction bracket, five-position tap switch for 25-, 70.7- and 100-volt applications.- Features
