Are these speakers any good??

At $300.00 list price, I don't think there are any better speakers than that on it's price range. Go for it.

One thing you need to remember is that sub doesn't look like it's powered so you might need amp for that Sub.
 
Yea thats what I was worried about. I might just sell the sub and buy a powered sub. Any recommendations for a decent powered sub that won't destroy my bank?
