I know this is an old thread, but I recently acquired a single G12-80 with the 444 cone. Dated 1979, so one of the first ones, it seems. Anybody who is into metal or hard rock should experience an old Celestion ROLA G1280 444 cone, IMO. This is a unique and awesome speaker for that. Skid Row is said to have used them, but Maiden and others come to mind immediately. Very different than the G12-65s from the same era - also great speakers if you find some good ones. The G12-80 is louder, clearer, and has great bottom, and a growling mid profile, with defined but slightly restrained highs. I've got it in a Friedman/Lynchbox 50 watt 1x12 combo now, and it is so damn pleasing.
