The JBL Control 322CT is a coaxial point source design ceiling Loudspeaker with a built-in 70V/100V multi-tap transformer, featuring a 12" low frequency cone performing as a waveguide for the high frequencies. The unique metal throat provides seamless transition to the horn, eliminating any aberrant HF "beaming", and resulting in consistent 90° coverage on a broadband basis with true coaxial behavior.
