I didn't mean the Ultra, but rather the Klipsch ProMedia 5.1 that you mentioned on the thread title.
Anyway, you might want to check
www.3dss.com for second-third-etc. opinions.
The folks there are pretty dedicated to their desktop speakers.
Edit: Oh yea, I forgot - it is to be expected, but just to say. The Creative Inspire series are in a different (lower) class than the ones mentioned so far.
