The SoundTube CM62-EZS-II is a compact, blind-mount in-ceiling speaker designed to simplify installations where plenum depth is limited. Instead of forcing a choice between full-range sound and a shallow ceiling cavity, the CM62-EZS-II delivers both — pairing a 6.5" treated-fiber woofer and 1" silk dome tweeter with a backcan just 3.5" deep.
Designed for commercial and institutional environments, the CM62-EZS-II provides a clean, flexible way to distribute paging and background music audio across 25V, 70.7V, or 100V systems, or as a direct 16Ω speaker. Each unit is UL1480A, UL2043, and CE listed for use in professional and public-facing installations.
Simplify Shallow-Ceiling Installations
The CM62-EZS-II fits ceiling cavities where standard-depth speakers won't clear ductwork, joists, or fire-rated barriers. This can reduce the need for custom backcan work or plenum modifications in retrofit and renovation projects.
The speaker accepts a 16Ω direct connection or steps down through a six-position tap switch for 25V, 70.7V, and 100V distributed systems. Tap selection should be based on the amplifier's output voltage and the total number of speakers on that zone.
Total zone wattage and speaker count determine the correct tap setting and amplifier sizing for the system.
Full-Range Coaxial Sound
The 6.5" treated-fiber woofer with cloth surround and 1" silk dome tweeter combine to produce a 75 Hz–22 kHz (±10 dB) frequency response with an 80° coverage angle at 10 kHz. This design helps maintain voice intelligibility and even coverage, which matters in spaces where the same speaker handles both paging and music.
The compact backcan measures 95.3 mm (3.75") deep by 245.6 mm (9.67") in diameter, making the CM62-EZS-II easy to incorporate into space-constrained ceiling installations.

- Hospitals and public buildings
Why Choose the SoundTube CM62-EZS-II?
The CM62-EZS-II makes it easier to spec a single speaker across a building that mixes retrofit and new-construction ceiling conditions. Its shallow back-can removes plenum depth as a limiting factor, while the multi-tap switch keeps it compatible with whatever distributed audio voltage the system already runs on.
When a project calls for consistent voice intelligibility and background music coverage without sacrificing installation flexibility, the CM62-EZS-II provides a straightforward, code-compliant option.
Why Buy from Audio Supply?
At Audio Supply, our team can help you confirm plenum clearance, tap settings, and amplifier zoning before you order. If you're specing the CM62-EZS-II alongside other SoundTube models or a distributed audio system, we can also help you work through total wattage and coverage requirements for the space.
