How to access caps on EPICURE Model Fourteen (14)

Trying to find a replacement tweeter for these guys, and decided it was a good time to re-cap. Problem is the circuit board (on which I assume the caps are located) is inside the front baffle, and for the life of me, I can't figure out how to access it. There must be a trick, right?

Anyone have any hints on doing the recapping? Or for that matter, know of any sources for tweeter replacement (not human speakers - price too high)?

Thanks in advance.

If I remember correctly you'll need to do 2 things. First remove the 6.5" woofer and the lower passive radiator - You'll have good access to the crossover which is mounted on the interior bottom or back panel . This board is connected via wires to the pot on the top front ( I can't remember if the cap is on the top or main panel or both but I think they are all on a small board and the wires only connect to the pot. If you need to service the pot you need to remove the knob - You my have to remove the front label to remove this pot Observe before diving in! This label may need to be peeled off the front very careful for reuse ( Hint use a very thin knife or putty knife and slide it back and forth - Do not crease the label as it made of plastic and can break or crease which will never lay flat. Once label is removed you need to pull off the plastic knob - Pull straight out as it is pressure fitted on a splined shaft. Once removed there is a nut that needs to be removed and allows the pot to be removed for servicing. I realize this sounds difficult but is rather straight forward. Go slow and enjoy. Epicure 14's are a nice speaker and I love'm Enjoy!

Sorry, @Mrpajamas but unfortunately on the fourteens, I'm 99% sure that the crossover is behind the tweeter control on the front baffle. I've got the speakers in front of me, and can't find any evidence of wiring behind the passive radiator or on the back baffle. (which i am - Baffled).
 
Thanks, @bradyzq Those pages are quite useful, and I may actually end up buying a tweeter from them. But as far as I can see, there's no actual mention about where in the cabinet the crossover sits. I have the parts to replace the caps, but I just can't get into position to access the crossover which seems to be on the front baffle, without an obvious way to remove it. I KNOW I'm missing something here. There must be a way.
 
If I understand the issue correctly, you cannot find where the crossover is located in the cabinet.

One trick I used for some Sansui speakers that had the crossover attached high on the baffle was to use my phone's camera and take pictures of the inside of the cabinet. I put a flashlight in the cabinet and, using the woofer opening, I pointed my camera at various places to discover where the crossover was located. Once located, I knew where to point the camera to get close-up images of the crossover. I took a lot of pics. Good thing it is so easy to delete unwanted pics. :D

Another option is to remove the woofer or passive radiator to access the inside of the cabinet. Follow the wiring from the woofer terminals to the rear terminals. From there you can follow the tweeter wiring to the crossover. You should be able to tell by feel if the crossover is attached to a board or if point-to-point wiring is used. My Epicure 20+ has a similar crossover (although a pot instead of a switch) and it is wired point-to-point on the back of the rear terminal cup. In your case, I expect that the crossover is at the switch mounted on the baffle as described above in post #3.
