I'm a big audiophile, and I've had crappy speakers on my computer for a long time now. Before that, I had a 200 watt system, but it just quit working. So, I've been saving up some money to buy a Bose computer system. I love it! You haven't heard music until you've head it through a Bose. I'm not paid to say that, this brand really is that much more awesome than everyone else. They use different technology than most of the other ones.
Edit: You won't find a wattage listing on Bose because they're just... different.
