Jbl Hartsfield (Older version) with Super tweeter and subwoofer. This speaker sounded very close to the Quad ESL 57 in the midrange (I had both at the same time) but could fill a theatre full of sound.
Most Apogee Full Range Ribbons (Full Range, Scintilla, Diva, Duetta,)
Many other great vintage pieces that the Japanese covet for good reason.
