Look for a book by Harry(?) Olson.
When he was at RCA around WWII, he did a good job at describing the practical
amenities of loudspeaker design.
Other than that, keep in mind that all you are trying to do is to drive a
parcel of air at an audio rate, with a plate (or horn) large enough to produce
the sound power you want without nonlinear effects due to the compressibility
of air. (196 dB = 1 atmosphere).
Most popular way has been a lightweight solenoid driven by reaction in a
magnetic gap--- the common loudspeaker.
Enclosures are merely to enhance the radiation over the lower range of
frequencies, the higher being effected by direct radiation fron the driven
plate ('cone').
Good luck!
