Soundtube CM42-EZS-II 4-Inch Coaxial Ceiling Loudspeaker (White) Soundtube

The 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 treated fiber 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.

Features:

• Engineered for applications with limited plenum space incorporating a Sound­Tube-specific shallow backcan with an installed depth of only 3.5 inches.
• One 4 inch (102 mm) treated fiber woofer with cloth surround and one 0.75 inch (19 mm) silk dome tweeter.
• Easy-access six-position tap switch for 25/70.7/100-volt and 16 ohm transformer bypass position allows for easy ordering, stocking and installation.
• Reduced amplification costs with maxi­mum efficiency including 87.5 dB sensitiv­ity and 16 ohm impedance.
• Superior voice intelligibility with an average coverage angle of 100° (2-10 kHz, independently verified).
• Cost-effective 16 ohm settings allows for the use of multiples of two, four, or six speakers in a system using a standard amplifier without a transformer.
• Incorporates a painted steel grille for lasting durability.
• Ceramic input terminal accepts up to 10 gauge plenum rated signal wire and includes thermal fuse.
• Suitable for use in voice alarm applications subject to EU regulations EN60849 and BS5839-8.
• EN54-24 listed.
• Clamping allowance from 0.00 in. (0.0 mm) to 1.50 in. (38.1 mm).

• Included accessories: Tile bridge, UL-listed 0.5-inch flex conduit clamp, paint shield and two wire nuts.

The CM42-EZs-II features a ceramic input terminal that accepts up to 10 gauge plenum rated signal wire and includes a thermal fuse for use in voice alarm applications subject to EU regulations EN60849 and BS5839-8.

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.

Developed specifically for the paging and background music applications where cost, quality and fit are paramount, the CM42-EZs-II is ideal for hotels, retail stores, restaurants, airports, churches (under eave), medical facilities or boardrooms. Indeed, the entire CM-EZ-II series is engineered for installations where high-efficiency and rapid installation are critical attributes. For applications requiring additional bass response, SoundTube’s CM1001dT subwoofer provides true low-end response down to 50 Hz.
