Patented BroadBeam Ring waveguide technology delivers a consistent dispersion pattern for maximum intelligibility and edge-to-edge coverage. One 8 inch treated fiber woofer and one 1.42 inch compression driver (1.0 inch exit) mounted to a proprietary cast-aluminum baffle and heat sink. High output and 120-watt transformer for the sound reinforcement and PA markets. Patented ZeroReflection enclosure technology for optimal sound reproduction and cabinet rigidity. Easy-access five-position selectable tap switch for 25-, 70.7- and 100-volt applications with transformer bypass position. Includes hanging hardware with galvanized steel cables and integrated SpeedClamp self-locking wire grip for fast, easy and secure installation. Also includes Euroblock connector and terminal weather boot. Average sensitivity of 94.0 dB offers high output capabilities and reduced amplification costs. UL 1480 (UEAY) and 2239 (hanging cable) approved.
