Hello!
That upgrade is quite a bit of fun. It's a fantastic improvement. I liked the speakers before, but the sound is SO much fuller and cleaner, now.
I enjoyed it a lot, but I don't know that my specific final configuration was actually the correct way to go about it. I had some minor differences in wiring it together between them (learned ideas from one applied to the other, which was a silly choice, in retrospect; should've made the same mistakes and kept them symmetrical... more learning...).
My actual networks ended up split across three boards, one for each driver, which makes for more wires crossing around inside the box than I really like. I'd try to streamline things and have as few meandering wires as possible if I did it again.
I have some horrible pictures of the inside I'll go find.... but I'm not that happy with the wiring. And there's cheesecloth everywhere.
I think Danny said it in his video, but these things are pretty tight, especially once you line 'em with NoRez.
I'll go find those pictures tomorrow.
Cheers!
