SoundTube CM82‑EZS‑II 8-Inch Shallow In‑Ceiling Coaxial Speaker with Short Can
The CM82‑EZS‑II is a compact, shallow‑depth 8″ coaxial in‑ceiling speaker designed for commercial audio installations where ceiling plenum space is limited. Available in black or white with a paintable micro‑flange grille, it offers full‑range sound for background music and paging applications.
It features a polypropylene woofer with butyl rubber surround and a 1″ silk dome tweeter, delivering wide 105° coverage using SoundTube’s BroadBeam Ring™ technology. A six‑position rotary tap switch allows for 25 V, 70.7 V, 100 V or 16 Ω direct mode operation. The reduced 3.75″ backcan depth enables installation in tight ceilings without sacrificing audio performance.
