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
