Description

The CM42-EZs is a 4” coaxial 2-way blind-mount in-ceiling speaker which delivers true high efficiency and perfor- mance across the operating bandwidth. By incorporating a 4" treated-fiber driver with cloth surround in a sealed drawn steel backcan, this speaker delivers maxi- mum frequency response (125 Hz – 22 kHz, - 10 dB) in a compact design.

Mounting hardware is included and features a constant-tension mounting

11w1m sensitivity determined using nominal impedance

2Frequency response measured in half or full space as dictated by speaker mounting configuration

3Max program power is 3 dB above max continuous power

4Continuous power rating, EIA-426-B test

5Max output based on max continuous power

6Max useable SPL based on testing by NWAA Labs
