It sounds like it would be much easier if you were back in
the
70's, with all those spectrum analyzers that were
available
back then.

Just because they aren't in the same form as they were then,
doesn't mean that they don't exist.

They came with a mic, and with pink noise or warble tones,
you
could get a rough look at what your looking for.

Modern stuff does more and has far higher resolution. Much
of it is computer-based.



You won't need much resolution since the damn speakers have no midrange or
treble.
I can get pretty good generalized response curves off my old Audio Control
and its cheap measurement mic.

As far as te anechoic chamber, that is not actually required. You can make
measurements in the back yard and get fairly good cures for speaker design
problems such as box tuning and beaming. its a good way to measure free air
resonance also
