Sound Reproduction: The Acoustics and Psychoacoustics of Loudspeakers and Rooms 3rd Edition
Hey that's how I got started as a loudspeaker engineer! David Weem's How To Design Build and Test Complete Speaker Systems* had a bunch of references to articles in the Journal of the Audio Engineering Society (AES), so I got an older friend who had just gotten a driver's license to drive me to Northern Illinois University's Physics Library and I photocopied out of like a 9" stack of Journal issue.
Later on my first job designing speakers the photocopier got used to make an entire copy of Richard Small's seminal thesis. That is a lot of pages but really good stuff and my huge recommendation if someone has PDF'd it online, or you pay to get behind the AES firewall.

Gotta note that before Thiele and Small, J.E. Benson published some really fundamental analysis in Amalgamated Wireless Australia. A lot of math if you are into that.
Martin Colloms' High Performance Loudspeakers has good stuff and I'll second the nomination of Vance Dickason's Loudspeaker Cookbook as really worthy. The 7th edition is much cheaper than the new 8th which I have not yet gotten.
*Which is really too simplistic so I can't recommend it, sorry David but thanks for the career! Well, really it was the crossover part which was incorrect, the rest still good maybe. The crossover formulas assume the speaker impedance is like a resistor but that is not so, it is way more complex than that.
