the question i recently put to Arny, how would you go
about
comparing different drivers for some loudspeaker design
(assuming a multi-driver setup) ? say, a tweeter:
you'll have different frequency range, different
frequency response, different sensitivity , different
dispersion, different power handling capacity, different
impedance, etc., etc.
now, say you'd have a perfect 10 Hz - 6 kHz 'lower part'
of the design ready, how to compare these different
tweeters ?

The way its commonly done is to build a number of complete
systems differing as little as possible given that each
represents the best you can do, including the various
alternatives.

for starters, you'll need different xo's for the drivers
so you're not _really_ comparing apples with apples
as some tweeters will 'use' more of the range produced
by the lower part than others :-)

This really isn't a stumbling block at all. The end goal is
to produce the system that best conforms to your
expectations. If you go into production with any of the
systems, of course your production model would include the
necessary variations in crossovers, etc.
