SoundTube CM82-EZs-II
8" Coaxial In-Ceiling 70V Shallow Backcan Speaker in White

OUR PART #  CM82-EZS-II-WH

Call for price! Not available online.


The Soundtube CM82-EZs-II is engineered for applications with limited plenum space incorporating a SoundTube-specific shallow backcan with an installed depth of 3.5 inches. One 8 inch (203 mm) polypropylene woofer with butyl rubber surround and one 1.0 inch (25.4 mm) silk dome tweeter. Easy-access six-position tap switch for 25/70.7/100-volt and 16 ohm transformer bypass settings allows for easy ordering, stocking and installation.

Reduced amplification costs and maximum efficiency of 88.0 dB sensitivity, 16 ohm impedance and a sealed enclosure. Superior voice intelligibility with an average coverage angle of 105° (2–10 kHz, independently verified). Cost-effective 16 ohm settings allows for the use of multiples of two, four, or six speakers in a system using a standard amplifier without a transformer. Incorporates a painted steel grille with rust inhibitor for lasting durability. Ceramic input terminal accepts up to 10 gauge plenum rated signal wire and includes thermal fuse. Suitable for use in voice alarm applications subject to EU regulations EN60849 and BS5839-8. Adaptable to ceiling thicknesses ranging from 0.04 inch (0.9 mm) to 1.60 inch (40.6 mm). UL 1480 (UEAY) and 2043, cUL, CE (EMC Directive 89/366/EEC, EN55020, EN55013) approved.
