Product Research

Features

Overview: The Soundtube CM42-EZ-II is a 2-way, blind-mount, in-ceiling speaker featuring a coaxially mounted 4" woofer and a 0.75" tweeter. The speaker features transformer tap settings for 25, 70, and 100 volt operation, and also includes a 16Ω bypass. Designed specifically for indoor paging and background music, the CM42-EZ-II is ideal for hotels, restaurants, airports, churches, medical facilities, and more.

Drivers: The CM42-EZ-II features a 4" treated fiber woofer with cloth surround along with a 1" silk dome tweeter, all mounted in a sealed steel backcan enclosure. This combination delivers high efficiency and performance across the operating bandwidth with a frequency response of 160Hz to 20kHz (-3db). Able to handle up to 20 watts RMS (40 watts Program power) and with a sensitivity of 87.5 dB, the CM42-EZ-II can provide clear powerful sound with a coverage angle of up to 170˚ @ 2kHz, and 100˚ average coverage angle @ 2-10kHz.

Enclosure: The CM42-EZ-II is housed in a galvanized steel backcan with an ABS plastic front baffle along with a painted steel-mesh grille. The grille can be painted to match the room color and includes an attached safety restraint lanyard. The CM42-EZ-II enclosure carries both UL1480A and UL2043 certifications and is CE and RoHS approved.

Mounting: Installation of the speaker is done blind-mount using Soundtube's constant-tension winged assemblies that come pre-mounted to the speaker. Once the speaker is slid into the ceiling opening 2 Phillips-head screws on the front of the speaker are tightened. This expands out the SpeedWing mounting arms providing tension on the backside of the mounting surface. The CM42-EZ-II can be mounted to ceilings ranging in thickness from 0.04 to 1.5 inches, including drop-ceilings using the optional Tile Bridge. Three secondary attachment points are provided on the back of the speaker for an additional safety line.

25/70/100 Volt: The CM42-EZ-II can be used in 25, 70, and 100 volt applications and includes a 16Ω bypass selection. A tap selection dial on the front of the speaker allows for easy configuration without having to remove the speaker from the ceiling. The following tap settings are available:

  • 25 Volt: 0.2W, 0.4W, 0.7W, 1.3W, and 2.5W
  • 70 Volt: 1.3W, 2.5W, 5W, 10W, and 20W
  • 100 Volt: 2.5W, 5W, 10W, and 20W
  • 16Ω

Terminals: A 4-position ceramic terminal strip is provided for wiring connections. One set of terminals provides the signal input while the other set provides a pass-thru for daisy-chaining multiple speakers. Each terminal can accommodate speaker wire up to 10AWG in size and includes a set-screw to hold the wire firmly in place.
