In addition to what jzwinck recommended, I'd also recommend the Loudspeaker Design Cookbook [0] and the Master Handbook of Acoustics [1]
If you're an engineer that's comfortable with differential calculus, I'd recommend the grandaddy of them all: Acoustics by Beranek [2] (I'm actually linking to Acoustics: Sound Fields and Transducers which is an updated version of Beranek's original Acoustics cowritten with Tim Mellow)
