I've got a pair of vintage loudspeaker units -- Wharfedale, made in England about 1968. They workded great for 40 years, but i just damamged the 15" woofers by cranking then music up to loud. These new amps and DVDs just weren't araound in 1968. Anyway, does anyone know where to get a replacement or have it "re-coned" (or whatever they call it)? The opening in the cabinet is 13-7/16" and the diameter is the outer "lip" where the driver mounts is 14-1/4" There are 4 holes for the mounting screws.
