I know nothing about audio / sound, besides you plug everything together and it works. I'm looking for some speakers on craigslist that I'm going to use mostly for listening to music and video games. How can I tell which speakers are valuable and will do what I want them to?
Examples of my confusion:
I saw these and they look like what I want. I think the same guy is selling this, but it costs 3 times as much and has fewer speakers. Which I don't understand. Can someone explain this?
Now this guy has a ton of stuff he's selling. These look the best to me, but obviously they're not since they're only $30. I was thinking, well maybe they're just broken, because then he's got these for $90 in "excellent" condition. But these dumb looking ones are $400?!
