In my simplistic view, the chamber behind the driver and before the throat needs to compress air in order for the horn to work. If the Vas of the driver isn't a lot bigger than the chamber, there won't be any compression, and it won't work like a horn (though it might work some other way).
In my setup, the Vas of the driver (Altec 515E) is MANY times greater than the compression chamber (1.1 cu ft.), and I get SPL of 115-118 db in the horn mouth with just a few watts.
I wonder if the ratio of Vas to chamber size is meaningful? Seems like it would be...
