The JBL Control 328CT is a coaxial 250-watt point source design ceiling loudspeaker with a built-in 70V/100V transformer, featuring an 8" 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 120° coverage on a broadband basis with true coaxial behavior.
