Not sure if this really belongs here, but figured I'd post anyway. This would probably be good info for anyone with a brief electronics background to learn some more. I took one or two circuits classes in college and I'm thinking about looking into this to support a few DIY projects I've been tossing around. Looks like there is some information in there specifically geared toward speakers/crossovers. https://www.kickstarter.com/projects/136425173/ece-202-203-electric-circuits-and-systems-ii-with?ref=category
