Features

Overview: The Soundtube CM52-BMG is a 2-way, blind-mount, in-ceiling speaker featuring a coaxially mounted 5-1/4" woofer and a 3/4" tweeter in a drawn steel backcan. The speaker features transformer tap settings for 25, 70, and 100 volt operation, and also includes a 16Ω bypass. Designed specifically for indoor background music, the CM52-BMG is ideal for hotels, restaurants, airports, churches, and similar applications.

Drivers: The CM52-BMG features a 5-1/4" polypropylene woofer with a rubber surround along with a 3/4" silk dome tweeter, all mounted in a ported steel backcan enclosure. This combination delivers high efficiency and performance across the operating bandwidth with a frequency response of 90 Hz to 20 kHz (-3db). Able to handle up to 20 watts RMS (40 watts Program power) and with a sensitivity of 87.5 dB, the CM52-BMG can provide clear powerful sound with a coverage angle of up to170˚ (@ 2kHz).

Enclosure: The CM52-BMG is housed in a drawn steel backcan with a ported ABS plastic front baffle providing added musicality with a bass response down to 65 Hz (-10 dB). Soundtube's BroadBeam Ring technology offers extended midrange clarity and ultra wide off-axis performance. The speaker includes a painted steel-mesh grill that can be painted to match the room color and includes an attached safety restraint lanyard. The CM52-BMG enclosure carries both UL1480 and UL2043 UL certifications and is CE and RoHS approved.

Mounting: Installation of the speaker is done blind-mount using a constant-tension fixed-wing mounting system. Two winged assemblies come pre-mounted to each side 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 mounting arms providing tension on the backside of the mounting surface. The CM52-BMG can be mounted to ceilings ranging in thickness from 0.035 to 1.6 inches, including drop-ceilings using the optional Tile Bridge (not included). Three secondary attachment points are provided on the back of the speaker for an additional safety line.

25/70/100 Volt: The CM52-BMG 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-teriminal ceramic barrier 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 12 gauge in size and includes a set-screw to hold the wire firmly in place.
