产品介绍
JBL Professional","Control 321C is a premium medium-power 300 mm (12 in) coax speaker , 250 watts, 34 Hz - 18 kHz.","Control 321C has been engineered from the ground up to deliver exceptional next-generation performance in a coaxial point source design ceiling loudspeaker. The low frequency cone performs as a true 12 inch (300 mm) diameter waveguide for the high frequencies. A unique metal throat transitions seemlessly to the horn to eliminate high frequency beaming which is common among this category of speaker. The result is a coaxial speaker with extremely consistent 90° coverage on a broadband basis.
