I had time to finish the crossovers last night. Soldering is my least favorite part of the whole building process, but if I have a plan and a repeatable process, it goes fairly smooth.

I'm kind of surprised there aren't more builds of them. I understand they are older, though.

There is some appeal of a ready-made package, especially the diysg pre-cut baffle. But part of the fun for me is everything from scratch. As much as saving money, I love making sawdust.
