The SoundTube CM62-EZ-II 6.5-Inch Two-Way In-Ceiling Speaker is a professional commercial loudspeaker designed to deliver clear speech and balanced music reproduction in distributed audio systems. Featuring a 6.5-inch treated-fiber woofer, a 1-inch silk dome tweeter, and a sealed steel backcan, the CM62-EZ-II is ideal for background music, paging, and general-purpose sound reinforcement in commercial buildings.
Designed for flexible installation, the CM62-EZ-II includes a built-in 32-watt transformer for 25V, 70.7V, and 100V systems, along with a 16-ohm transformer bypass setting for compatible low-impedance amplifiers. This allows the same speaker model to be used in a variety of commercial audio installations.
With a 65 Hz–22 kHz frequency range (-10 dB), 90 dB sensitivity, and a maximum output of 107 dB SPL, the CM62-EZ-II provides dependable performance for restaurants, retail stores, hotels, conference rooms, schools, and other professional environments.
Its blind-mount installation system, constant-tension mounting wings, and included steel tile bridge simplify installation in compatible drywall and suspended ceilings.

Clear Speech and Background Music Reproduction
The SoundTube CM62-EZ-II is designed for commercial environments requiring consistent sound coverage and reliable speech intelligibility.
Its coaxial two-way design positions the high-frequency driver with the low-frequency driver, providing a compact sound source for ceiling installations.
The 6.5-inch treated-fiber woofer with cloth surround reproduces midrange and low-frequency content, while the 1-inch silk dome tweeter handles high-frequency detail.
This combination makes the speaker suitable for background music, paging announcements, and general-purpose distributed audio.
The speaker's published frequency response is 125 Hz–20 kHz (±3 dB), with an extended range of 65 Hz–22 kHz (±10 dB).
For installations requiring greater low-frequency output, a compatible subwoofer may be added as part of the overall system design.
Flexible 25V, 70V, 100V, and 16-Ohm Operation
The CM62-EZ-II features an integrated transformer with selectable power settings for commercial constant-voltage speaker systems.
The available settings include:
| Speaker System | Available Power Taps |
|---|
| 25V | 0.3W, 0.5W, 1W, 2W, 4W |
| 70.7V | 2W, 4W, 8W, 16W, 32W |
| 100V | 4W, 8W, 16W, 32W |
| Low Impedance | 16-ohm transformer bypass |
The convenient rotary tap selector allows installers to configure speaker power according to the amplifier and system requirements.
For larger commercial installations, multiple CM62-EZ-II speakers can be connected to a properly sized 70V or 100V amplifier.
The 16-ohm bypass option provides additional flexibility for compatible low-impedance systems.
Important: The 50W continuous and 100W program ratings apply to the speaker's direct low-impedance operation. The integrated transformer is rated for a maximum of 32W.
Wide Coverage for Commercial Spaces
The CM62-EZ-II is designed to distribute sound across a broad listening area.
SoundTube specifies the following coverage measurements:
- 135° at 2 kHz
- 120° at 10 kHz
- 80° average coverage from 2–10 kHz
These measurements help audio system designers determine speaker placement and spacing for different environments.
In restaurants, retail stores, offices, and other commercial spaces, proper speaker spacing can help provide consistent background music levels and intelligible announcements.
Actual coverage depends on ceiling height, room acoustics, speaker spacing, and system configuration.
Sealed Steel Backcan and Easy Ceiling Installation
The SoundTube CM62-EZ-II includes a sealed drawn-steel backcan and an ABS front baffle for professional ceiling installations.
The integrated enclosure eliminates the need to purchase a separate conventional backcan for the speaker.
Its constant-tension winged mounting system secures the speaker to compatible ceiling materials, while the included 21-gauge steel tile bridge provides support for suspended ceiling installations.
The CM62-EZ-II accommodates ceiling material thicknesses from approximately 0.04 to 1.60 inches.
A painted steel grille provides a finished appearance suitable for commercial interiors.
The speaker also includes a UL-listed flexible conduit clamp, paint shield, and installation hardware.
