Need a great sound system: Kicker KB6000 full range vs Kicker ik501?

I don't know much about audio speakers at all, but I need to be able to play music for some smallish events at my house. I don't need a full sound system, I just need something that will connect to my iphone or laptop and play well. Just looking for speakers that are clear, strong bass, good for electronic and dubstep, and fairly loud. I really like everything I've heard about Kicker IK501, but I saw the KB6000 full range on their website, and I could get 2 of them for the price of the kicker IK501.

Just looking for a little insight for a guy who knows very little about sound, but who has an appreciation. If you have any other product suggestions that might be better, please throw it out there, though my price range can't go much higher than $200.

Ok sure
