Q: What makes a CDT-1or CDT-2 a CoEntrant Driver and not a Coax?
A: A compound phase plug combining the HF and LF outputs into one horn throat!

As in conventional loudspeaker with seperate drivers, the CoEntrant compression driver reproduces the frequency decade from 1800Hz-18kHz.

The h.f. compression driver feeds through the cone midrange via a tube, which allows it to couple to a conventional or Complex Conic horn.

The CoEntrant midrange extends the transducer´s operating range to as low as 350Hz - dual surrounds attach the cone securely to the frame and the throat extension.

The phase plug combines the high and midrange frequencies - both enter the horn with minimal time offset.

This patented topology produces a true point source transducer with: 1. Extended operating range, 2. Lower distortion, 3. Controlled and even coverage.
  • An 8”or 10' MF cone and a 1”or 2"
HF compression driver combine in a
2”or 3" throat

• The driver combination offers wider
bandwidth and higher power handling
at mid frequencies

• Much improved sound quality over
a 2” compression driver

• Power Handling of 350/500 watts
