I would be interested to hear what these are and in what way they are
better other than box size.


I suppose there's many ways to skin a cat. My preference (shaped by
price and space too) over the years has come down to sealed box or
transmission line. Wonder what Don has in mind.

From his subsequent postings, the only alternative is horn loading.
This suits short throw drive units but a 30 foot horn, even when
folded, is a rather large beast to shoehorn into the typical domestic
auditorium (living/ entertainment room) of your 'average semi'.


Well not if you put the driver and throat under the floor and just vent
the mouth - remember at those frequencies the sound has little or no
directionality.


Something like this?
