Allsmiles,
I would open things up and check the xover and wiring to the tweeter. Yes, you need to take the woofer out to get to the xover. Since you are not getting sound from both, I highly doubt that something is wrong with both xovers. I think that the diaphragms are gone.
It's easy to call Klipsch up and get replacement diaphragms. They are less than $50 each and come with directions to install. If you even a little handy, you should be able to install them yourself. If you need help with it, drop me an email and I'll help you out.
