CM42-EZS-II-BK
Soundtube CM42-EZs-II Coaxial In-Ceiling Shallow Backcan Speaker in Black
Designed for applications with limited plenum space incorporating a dedicated SoundTube shallow backcan with an installed depth of only 3.5 inches. A 4-inch (102 mm) treated fiber woofer with fabric surround and a 0.75-inch (19 mm) silk dome tweeter. Easy access to six 25/70.7/100-volt tap positions and a 16 ohm tap transformer allows for easy ordering, stocking, and installation. Reduced amplification costs with maximum efficiency including 87.5 dB sensitivity and 16 ohm impedance. Superior vocal intelligibility with an average coverage angle of 100 (210 kHz, independently verified). The cost-effective 16 ohm configuration allows the use of multiples of two, four, or six speakers in a system using a standard transformerless amplifier. Incorporates a painted steel grille for long-lasting durability. The ceramic input terminal accepts up to 10 gauge plenum rated wire leads and includes a thermal fuse. Suitable for use in voice alarm applications subject to EU regulations EN60849 and BS5839-8. EN54-24 listed. Clamping allowance from 0.00 in. (0.0 mm) to 1.50 in. (38.1 mm). UL 1480 (UEAY) and 2043, CE (MEM Directive 89/366/EEC, EN55020, EN55013) approved.
Included Accessories: Choose from a tile bridge or pre-construction support, 0.5-inch flex conduit clamp, paint guard, and two wire nuts.
