Yes nothing on the tweeter or woofer. All drivers are two wires straight to the binding post.

I can find what looks like the exact 3.3uf 50v nichison non polarized capicitor. Too many choices so I'm not sure what a suitable upgrade would be. I'm tempted to just try something on the tweeter just for fun as long as it's not too much money. $20 a cap would be okay but less is even better.

Is the tweeter a piezo type? - Brian H P 12:29:19 06/14/23 (2)
That would explain the lack of a series cap. Piezo elements are inherently capacitive, hence naturally highpassed, and don't need a filter.

But it LOOKS like a dome. If it has a conventional voice coil, it must have a series cap (maybe concealed internally?), or I don't see how it could long survive a fullrange signal from the amp.

  It's a paper dome with a stamped steel enclosure. It's certainly possible something is hiding in there. I'll try to get a look in there when the new mid range cap arrives.

your pics are too small - Story 16:08:12 06/09/23 (1)
and it's possible the cap for the tweeter is mounted to a circuit board inside the enclosure so get out the flashlight

  No circuit board inside. Drivers wired straight to the binding posts. One midrange cap literally the only thing besides the drivers themselves.
