Specifically, I looking for a 15" woofer with the model number 583976. I found one in a Magnificent console, but I really need a pair. If you have it, I could buy it form you or do an exchange: I have a more-popular (easier to sell on Ebay) 15" woofer with the model number 583903 in perfect condition. I would cover all the shipping fees for the exchange and even chip in a small fee for your inconvenience. Thanks!
