"The overall horn pathway length is whatever it works out to being defined by the throat size and the mouth size. Essentially, the pathway length is whatever is needed to get from point A to point B while maintaining the appropriate expansion rate(s)."
True, if you're building a 'perfect' horn, which, practically speaking, usually means an fc of 100 Hz or higher. Going lower space considerations more often than not make compromises a necessity. In that case I've found that path length trumps flare and mouth area in terms of getting the lowest extension possible from a box of finite size. At the expense, of course, of broadband sensitivity and ripple free response.
