I'd get these...Logitech makes good stuff. Cheaper, and almost 2x the watts and you get an actual sub.

I have the Z-5500's (totally different category, I know - but still Logitech) and a bunch of other Logitech stuff and all of them are great. I've never had a bad experience with Logitech - always great stuff for a great price, so I always recommend them.
