I bought some cerwin vega home speakers from a friend, the sticker on the front says "d9" they have a 15" woofer, 2 mids, and 1 tweeter each. What can you tell me about them? how much power can they take, are they worth a shit, etc etc. I do have one problem with one of them for sure, the crossover on one is not functioning properly as its letting all frequencies come through the woofer. Also they both have small tears in the surround but I think I can patch them. All total I paid $50 for the pair, good deal?
