Control 321CT 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 90º coverage on a broadband basis. The transformer version Control 321CT comes with a pre-attached top quality, low saturation 60 Watt multi-tap transformer for use on 70V or 100V distributed speaker lines.
