Product Information

The Soundtube CM42-EZs-II is a 4-inch, coaxial, two-way, blind-mount, in-ceiling speaker which delivers true high efficiency and performance across the operating bandwidth. By incorporating a 4-inch treatedfiber driver with cloth surround in a sealed drawn steel backcan, this speaker delivers maximum frequency response (125 Hz  22 kHz, - 10 dB) in a compact design.

Mounting hardware is included and features a constant-tension winged 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 (orange) tile bridge, optional pre-construction bracket, and a six-position tap switch for 25, 70.7 and 100-volt applications with transformer bypass position.
