I've been listening to a lot more music on my main PC lately and I was thinking that I could probably do a lot better soundwise than my well-aged Altec Lansing ACS33 setup (two micro-satellites + subwoofer). Reading reviews, I saw a lot of good things said about Klipsch ProMedia Ultra 2.0 speakers. I've had them now a couple of days and they sound pretty darn great.
There's no subwoofer, but they crank out surprising levels of bass. The bass isn't ultra-deep, but more than adequate for casual listening and regular computer work (serious gaming requires surround sound or headphones). All other frequencies are quite nice and tight -- overall, you get a pretty rich sound from these very reasonably priced speakers (under $100). A couple of nice features seal the deal, including front-mounted headphone and line-in jacks as well as a separate bass control knob.
Available in black or silver, they also have removable front panels (for that serious "damage me, I'm naked" look). And at just over 10" high, they're big enough to let everyone know that you're serious about your sound quality, but not so big as to make people wonder if you're compensating for something.
Everything seems to be of the high quality one would expect of the Klipsch name. As long as these are for casual listening, and you aren't expecting $500 bookshelf speaker sound quality, you will be hard pressed to do better than these Klipsches. Highly recommended!
Update (3/1/2008): The volume knob is failing electronically, creating static and decreasing the sound quality of what comes out of these speakers. I'm not very happy about that, as there's no way to fix it myself. Less than three years isn't a very reasonable lifespan for something of this supposed quality. :-/


I have the same problem. The speakers will only produce a full sound if the volume knob is adjusted just right--it would appear to be an electrical short in the volume/power control component. Have you found any solutions?
