(context...looking for a good speaker that is as small as possible
for some specific sounds).

FWIW...

It would be great to find a speaker with a "flat" (+/- 1.5 db?)
response from about 500Hz to 10Khz.  Below 500Hz it could fall off
steeply...above 10Khz a gentle slope (6db/octave) would be nice.

It would good to find one like the above but with a "flat" response
from only about 1Khz to 7 Khz.  Especially if below 1Khz the curve
wasn't too sharp.

Since they don't have to be used with an arbitrary signal (I
predetermine the sounds) I won't need to use a LP filter (part of a
crossover) to protect the speaker from bass signals...I think...

But at this point I am thinking I should just buy a bunch of speakers
and listen to them with my intended signal and pick out the best
one...hate to end up with a (n-1) speakers I can't use though...
