KLH model 6

[Ironic Dragon]

I've got a pair of... let's call them well loved... model 6s. Caught them just before they hit the dumpster at a church clean out. One's missing the burlap gill cloth, and both are sporting dead tweeters. I would absolutely love to replace the tweeters and check up on the crossover, but there seems to be no way into the cabinet, what with the woofer glued in from behind, and the box being assembled with finishing nails.

Anyone have any help for me to get them back to full working order?
