1) Klipsch Promedia 4.1 ~$230 (power/quality)
2) Altec Lansing 641 ~$130 (quality)
3) Logitech z-560 ~130 (power)
The Logitech and Klipsch are rated higher as far as wattage than the 641's. But the 641's and Klipsch are the ones that feature tweaters (allow for more distinct high pitched sounds). I personally got the 641's as I wanted quality and since it's till over 200 watts, it was more than enough power for me. At full volume I can shake the whole house. So I can't even imagine what the Klipsch would produce, but if you want to save money and retain quality, I'd get the 641's.
