12-inch two-way full-range coaxial ceiling loudspeaker system is a two-way loudspeaker with 12-inch (30.5cm) low frequency cone and high temperature voice-coil assembly coaxially mounted with wide-dispersion dome radiator tweeter. It utilizes a dual-section crossover network centered at 2500Hz that provides 12dB/octave of attenuation for each element outside its operating range. Clear, intelligible speech and fine music reproduction are ensured by the extended 90Hz to 18kHz frequency response. Mounting holes are provided on the rear of the woofer magnet to mount transformer to operate the loudspeaker from 70.7/100V distribution lines. The 920-8B's frame also allows the loudspeaker to be front-or rear-mounted. It is equipped with 4-pin phoenix-style connector which enables easy pass-through wiring of up to 12-gauge wire. This allows for quick and secure hookups and long-term reliable operation. It is the ideal loudspeaker when high-efficiency, wide-dispersion and easily mounted full-range loudspeaker is required for in-ceiling or in-wall installations.
