The SoundTube CM82-EZ-II 8-inch In-Ceiling Speaker is the next generation version of the CM82-EZ with improved and additional features. It has one 8.0-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, 89.0 dB sensitivity, 16 ohm impedance, and a sealed enclosure. Superior voice intelligibility with an average coverage angle of 95° (2 - 10 kHz, independently verified). Cost-effective 16 ohm settings allow 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 a 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.
