Definitely an upgrade! Of course if you like the brighter Klipsch sound then maybe you won't like the laid back sound of the RC-10's.
The frequency response of the Promedia is 31hz to 20khz because of the subwoofer. Of course can that sub really hit that low?
Since the RC-10's are only bookshelf speakers with no sub the low end is probably around 50 or 55hz.
Published specs are one thing, actually hearing the speakers in person is quite another.
I wouldn't think twice about upgrade but I own 4 RC-10 speakers.
How much are you willing to spend on a amp/receiver to pair with the RC-10s?
