Beautiful work. I like your choice of capacitors. Mundorf, at least to my budget, are my favorites. I've used quite a few of the EVO Oil caps in speaker rebuilds, and have always liked their sound. I'm using a mix of Supreme EVO Oils and ClarityCap CSA's, on a current project. Hope to get it completed soon.
Also, I've never done recaps, on both vintage or new speakers, where the recap didn't improve the sound. I've only done like for like recaps. Never anything to mod or change from stock values, and never been disappointed. And I do A/B the stock speaker, to a recapped speaker, for comparison. I even volunteer family members, for an extra set of test ears, and they hear positive differences between the two. So, I don't shy away from tearing into a speaker, if the base design is worthy of the upgrade? Part of the fun.
