I have a pair of Cerwin Vega V-12F speakers and my receiver at the moment cannot play them to their best quality, and I was wondering what I should buy to power these speakers. I don't want to spend a whole lot, just looking for something that is enough to play these big guys. I'm not really familiar with how much power these speakers take in, because I got them for free from a relative. I know that they work, and my receiver right now can't hand them. Any help is appreciated! Thanks.
