what do you guys think of cerwin vega drivers ? im asking because they go relativly cheap on ebay, and im looking into possibly building some new speakers. there about 25$ for (2) 8" woofers. about 40$ for a pair of tweeters, 25 for crossovers, 75$ for (2) 10" woofers, and about 30 for a pair of 6" mids. think they could make some sturdy speakers givin the right drivers are matched together ? think it would make a sturdy set of speakers that sounded pretty good or would it be a big waste of money ?
