I've heard only a couple of brands of speakers at my local Circuit City, and the very best ones I've heard so far have been the Infinity speakers. The ones they had on, were the IL-30s I think. I wanted to go with the IL-60s because of the bigger subs, but I keep hearing all of these negative things about having powered towers, especially when you already have a great sub. Right now I have an SVS 16-46 PCi, and already am in the process of getting a B4+ so I'm not sure that I need to have powered towers anymore. So, I was thinking about going with the Alpha 50s. I have NEVER heard the Alpha models. Are they similar in sound to the Interlude? Also, what are your guys' opinions on the Infinity Alpha speakers? What kind of price range am I looking at, and where can I find them for the lowest price, while still being brand new?
