This group has been over this quite a bit recently.  The thing to do is
get reference sources.  There appear to be two main ones: a book by
Martin Colloms called "High Performance Loudspeakers," and a magazine
called Speaker Builder.  I recently bought the Colloms book, and it is
excellent, for novices or experts.  I have had good experiences with
Speakerlab but others on the net haven't, in particular that their drivers
didn't measure out to published specs and weren't consistent.

Are your preferences based on solid facts or religion?  In other words,
have you done enough research to decide on implementation already?  From
your earlier quote, I would say probably not.  If you have, never mind.
For instance, if you want great fidelity, horns won't do.  If you want
high efficiency, horns are the best choice.  And if you're looking for
extended bass response AND high efficiency, enclosure volume is the main
determining factor.  On the other hand, if you want massive sound volume
you want a big woofer.  Etc., etc.  It's all very complicated.
