So, I just picked up a huge steal today. Found a pair of Advent Large Loudspeakers (10" Driver). They are in perfect condition. Surround has no wear..might have been replaced. Tweeter still has the manufacture date on it (Nov 10 and Nov 11 1975). I have them hooked up to a cheap Pioneer Reciever right now, but they still sound fantastic. They even have the original Stickers on the back listing proper wiring and placement along with the warranty card.
The best part about it..I found them at Goodwill for $4.99 for the pair. :D :D
