Well, im wondering if any of you have any links to some good reads on enclosure design theory. I used to have some good ones on horns and transmission lines and a bit on ported, but my comp crashed and i lost it all before i got around to reading it all. Well, ive had my new car since august, and im finally done paying off enough of my debts to start saving. Im going to need to be building a new box, and i think im going to play with the subs i have and experiment with them. I am most interested in bandpass design theory. If you have any links to some good info on design theory, please share.
