Just wanted to give a quick update on my progress: I put everything back together. Here a shot of the installed recapped crossover with terminals in the back. I put the terminal in a location covering the original cable feedthrough so I would not have a hole to plug in the back wall:
One note regarding using a hole saw on the back panel: The side walls are exactly 15 mm thick, i.e. this needs to be taken into account when marking the center spot for the hole saw. Otherwise it is easy to accidentally cut into the side walls if one wants to stay next to the wood slat that holds the crossover...
Here a shot of one of the speakers after reinstalling the woofer:
I am listening to Herbie Hancock's Maiden Voyage...very nice! It seems the mid and treble speakers are in good condition. Both speakers sound the same, i.e. it appears this worked out nicely!
Thanks for your help and input!
Now on to the broken cover. Seems the previous owner was not able to restrain his curiosity and broke one of the covers while trying to pry it off...Something for the next weekend...;-). I am thinking of using small magnets to hold them in place once they are fixed instead of the double sided tape...
