Can you explain your goal a bit more?  What do you mean by "design
a loudspeaker from fundamental acoustics laws"?

For example, suppose your primary goal is to reproduce the same
music in your listening room that you heard in a concert hall.  
Your first step would then be to build a model human head with a 
microphone in each ear socket.  You would then take this to your
concert hall and make the recording.  Unfortunately, when you play
that same music through your loudspeaker at home, the room acoustics
cause the sound you hear to be different than what was recorded in
the concert hall.  Thus, no loudspeaker design can achieve exact
reproduction of sound without first controlling the room acoustics
(i.e. use a pair of good headphones).

If your primary goal is to build a loadspeaker that creates an
acoustic sound pressure wave that is equivalent to the applied
voltage, you must first realize that speakers are mechanical devices.
Any real mechanical device has non-ideal (and non-linear) properties
that prevent the speaker from operating perfectly.  Of course,
the defects may be so small as to be imperceptible to the human ear.

As I say, I am not sure what you mean by "design a loudspeaker from
fundamental acoustics laws".   Can you be more specific about your
request for info?

In any case, I also recommend Beranek's book on Acoustics.  The
modeling techniques can be applied to any system.  At MIT, we use
these techniques in Bose's Acoustics class to model loadspeakers as
well as ported speaker designs (as well as many other systems).
