My choice is rather esoteric, and I'm not actually sure of the manufacturer of the driver itself, but it's the speaker that came stock in a 1972 Plymoth Valiant. These were mono speakers so you'll need two of them. Talk about your magic midrange! Only drawback is you need to have a pretty large listening room to park two Valiants with the doors wide open in the proper configuration for sterophonic listening. I've got mine 10 feet from the back walls and four feet from the side walls. Front doors open, rear passenger door closed with the window open. I'm running them with the best amplifier ever made (IMO, of course), which comes integrated with it's very own turntable. Yep, you guessed it, I'm running those puppies through my vintage Kenner Close'N"Play turntable. I've got an output tube buffer on it, a $5K aftermarket power cord, and some $9K speaker cable. I'll leave the latter two for an appropriately ostentatious thread.
