Some physical limitations had taken me out of the speaker building business. Up for sale is a couple of my books
1) Speaker Enclosures by Alexis Badmaieff and Don Davis (144 pages, softcover, copyright 1966)
2) 21 Custom Speaker Enclosure Projects You Can Build by David B. Weems (251 pages, hardcover, copyright 1980) Asking $12 delivered for both
One of the cooler projects in the fist book is the Jensen Imperial Folded Horn. It's the one I always wanted to build but just never got around to it.
I don't visit here every day so the best way to contact me is by email at: jeff DOT hoak AT gmail DOT com
Thanks for looking!
