Patented BroadBeam® waveguide technology delivers a consistent dispersion pattern for maximum intelligibility and edge-to-edge coverage. One 5.25 inch polypropylene woofer and one 1.0 inch convex titanium tweeter with FerroFluid cooling mounted to a proprietary cast-aluminum baffle and heat sink. Rapid-installation, blind-mount, fixed- wing mounting mechanism with constant-tension design affixing to ceiling thicknesses ranging from 0.25 inch (6.4 mm) to 1.91 inch (48.5 mm). Easy-access six-position selectable 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. Steel grille with protective powder-coated finish for lasting durability. Average sensitivity of 86.5 dB offers high-output capabilities and reduced amplification costs. UL 1480 (UEAY) and 2043 approved. Included accessories: Tile bridge, conduit plate, Euroblock connector and paint mask.
