Patented BroadBeam Ring waveguide technology delivers a consistent dispersion pattern for maximum intelligibility and edge-to-edge coverage. A 66-watt transformer and high output for the sound reinforcement and PA markets. One 8.0 inch treated fiber driver and one compression driver with a 1.0 inch exit mounted to a proprietary cast-aluminum baffle and heat sink. Rapid-installation, blind-mount, fixed-wing mounting mechanism with constant-tension design affixes to ceiling thicknesses ranging from 0.25 inch (6.4 mm) to 1.91 inch (48.5 mm). Easy access six-position tap switch for 25-, 70.7- and 100-volt applications with transformer bypass position. Separate tool-free magnetic grille and bezel assembly with integrated safety cable for ease of install and in-field painting. Average sensitivity of 93.0 dB offers high-output capabilities and reduced amplification costs. UL 1480 (UEAY) and 2043 approved.
