Summary: I purchased these after a lot of research. The kids speakers (on a second PC) went belly-up, so I gave them my Logitech 2.1 set - and ordered the T20-S2 mainly for the smaller footprint (no sub), and also for the increased clarity.
BTW - the price above was NZD converted to USD at the time of purchase. Audio in NZ is normally relatively expensive compared the the rest of the world.
Pros: Good size, nice design, good mids and highs, very good clarity
Conclusion: All in all, are they a good value? Not necessarily, but they sound awesome for most things. Lovers of hip-hop, industrial, death metal, or any other music genre that is heavy on thick, thumping bass, should probably steer clear.
Summary: I got these to replace a pair of Klipsch Pro Media Ultra 2.0 which I gave to my 79 year old father in law. The Klipsch had better highs and a brighter overall sound which he could hear better. I like these because they have a nice smooth sound given the silk dome tweeter and for $100 I really can't complain. I suspect the M Audio series is better at their new lower price point but these are more compact.
