The JBL Control 321C is a coaxial point source design ceiling loudspeaker, 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.
