I am going to get a speaker system primarily to play music out of. The music that I will play is usually going to be low to medium quality MP3 files that are downloaded. I am looking for a speaker system that will give me really good sound with good bass. Does anyone have any suggestions for a system that would be less than $450? I have been looking around and trying to find some deals on Craigs list and ebay, but I see some speakers that are somewhat expensive, but I read that they need a very powerful (and expensive) reciever to pwoer them.

So if anyone has a combination that would work well, I would really appreicate it. Thanks.
