For affordable horns, the most obvious answer is Klipsch.
Since 1945, the people at Klipsch have improved the components in their Heritage line products. Including the Klipschorn.
I beg to somewhat disagree: the old Klipschorns used alnico drivers. Alnico is now ruinously expensive (at least, cobalt is) and for the past 30 yrs or so, the driver quality has had=to go down. IMO, etc. Regards
