I am sure many of these types of threads may follow if you have been on the fence about a crossover rebuild. The gimpod boards and website make this project like "paint by numbers". Read the website, make a parts list, order and assemble once parts arrive. I did this for my SDA 2.3
Sonicraft for caps and resistors on sale $265
Gimpod boards $100
Mouser clips and mounts $ 25
Tape/zip ties/etc $ 10
Solder / de-solder tools ? borrowed $ freebee
Ballpark cost $400
I have attached photos of a stock board, photos of a rebuild on a stock board, and my project on the gimpod board. I don't recall who's stock rebuild this was. I either got it from a thread or a member emailed it to me. It was going to be my roadmap as I saw a lot of others with worse positioning and liked this one the best. On the gimpod board, the space and location issues go away.
I also found my stock board hanging from the large inductor by like 2 clips when I opened the passive.
