I am new to the forum.
Many years ago, when I was a poor college student, I designed and built a pair of enclosures for a set of 12 inch electrovoice woofers, mid range horns, radio shack peizo tweeters. They were a bass reflex design, 5 and 1/2 cubic foot interior. They sounded pretty good.
Life goes on and I no longer own those speakers. I would like to get back into designing and building a small set of speakers.
What I need is to find the book with the basic formulas for a bass reflex enclosure. It was tough to find back in the 70's. Any information on an old reference or a new one for a newbie or slightly advanced newbie would be appreciated.
