SoundTube - CM82-EZ-II - 8" Coax In-Ceiling Speaker (Single)

The next generation version of the CM82-EZ with improved and additional features. 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 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. Included accessories: tile bridge, UL-listed 0.5-inch conduit clamp, paint shield and two wire nuts.

The CM82-EZ-II is an 8-inch, coaxial, two-way, blind-mount, in-ceiling speaker which delivers true high efficiency and performance across the operating bandwidth. By incorporating an 8-inch polypropylene driver with a butyl rubber surround in a sealed drawn steel backcan, this speaker delivers maximum frequency response (65 Hz – 22 kHz, - 10 dB) in an integrated enclosure design.

Mounting hardware is included and features a constant-tension, fixed-wing mounting system with a 21-gauge “fullmetal” steel tile bridge ensuring rapid and secure installation in any sheetrock or drop-tile application. For easy ordering, stocking and installation, this series includes a color-coded (green) tile bridge, optional pre-construction bracket, and six-position tap switch for 25-, 70.7- and 100-volt applications with transformer bypass position.

Developed specifically for paging and background music applications where cost, quality and fit are paramount, the CM82-EZ-II is ideal for hotels, education, healthcare, retail stores, restaurants, airports, churches or boardrooms. Indeed, the entire CM-EZ-II series is engineered for installations where speech intelligibility, high-efficiency and rapid installation are critical attributes. For applications requiring additional bass response, SoundTube’s CM1001d-T subwoofer provides true low-end response down to 41 Hz.
