OVERVIEW
- Engineered for applications with limited plenum space incorporating a SoundTube-specific shallow backcan with an installed depth of 3.5"
- One 8" (203 mm) polypropylene woofer with butyl rubber surround and one 1.0" (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
- Adaptable to ceiling thicknesses ranging from 0.04" (0.9 mm) to 1.60" (40.6 mm)
- UL 1480 (UEAY) and 2043, cUL, CE (EMC Directive 89/366/EEC, EN55020, EN55013) approved
- High-quality black or white painted finish. Custom colors available
- Included accessories: tile bridge, UL-listed 0.5" conduit clamp, paint shield and two wire nuts
- Optional accessories: color-coded (green) pre-construction bracket (AC-CMEZ6/8-PCB) and junction box (AC-CM-EZ-JBOX)
