The CDT-2 CoEntrant Transducer was developed to deliver reference quality sound to very large audiences. CT7’s have vented 15" woofers, CT9’s a horn-loaded 15" woofer for higher output and more even dispersion.

CT7215’s have a dual-15" doublet source for low-octave vertical pattern control: the CT9215 adds a horn-loaded 10" midrange for maximum output.
