Description

The CM-EZ-II is a 2-way blind-mount in-ceiling speaker. The CM-EZ-II speaker design incorporates an 8" polypropylene driver with rubber surround and a 7.3 liter steel backcan for extended frequency response (54 Hz – 22 kHz, - 10 dB). SoundTube’s integrated CM-EZ-II design includes unique & patented blind mount SnapCam™ installation technology and a 21-gauge steel tile bridge ensuring rapid and secure installation in any sheetrock or drop-tile ceiling. For easy ordering, stocking and installation, the CM-EZ-II comes with a 6-position tap switch for 25, 70.7 & 100 V applications with voice coil/8 Ohm bypass.

Applications

Engineered for general background to foreground music & paging applications, the CM-EZ-II is ideal for retail stores, restaurants, airports, churches, conference centers & boardrooms.
