Klipsch used CTS at times as well as Eminance and other suppliers. The square ones cold be K33E's made by Eminance they also used Stephens ,EV , occasionally JBL and University in the 50's and 60's

CTS made a lot of square magnet drivers, so the ones on the left could be CTS.

Are there any numbers stamped on them? If you can post those they can be decoded (by people smarter than me).

The grey stickers on the pair on the right tell me they were made by Eminence.
The square magnets on the left pair is common for CTS. Both companies used the same frames.
