Carver did not design those tweeters, designed by Hi-Vi and cloned by even cheaper manufacturers. See bottom post:

Also, as far as I recall, the Apogee was spectacularly different and difficult to drive compared to the Magnepan and Hi-Vi designs. I've never gotten close enough to inspect Apogee or Magneplanar's so I'll defer to those of you who have.
Best,
