I have a copy of the book with me...bought it from madisound when they were selling it for 11$...but there are tons of information floating around on the web regarding speaker design...download WinISD and fool around a abit to see how different parameters affect the freq response and phase shift..will give you a general idea and starting point..also what type of speakers you wwant to design matters, open baffle, TL, Dynamic, electrostatic, Hybrids, single driver, horn based..etc.
