no problem. Unless you are into bleeding ears, it will be extremely rare that you would push your receiver to anywhere near a sustained 100 watts RMS output. There will be moments where the power could increase dramatically, but then that is why the Klipsch rating includes a "peak" value....it is for transient spikes in output power required by the music reproduced.
If you are using a powered subwoofer, then most of the heavy output power that would have been required by the speakers to reproduce low frequency sounds will be handled by the subwoofer. That means there is even less chance of approaching the speakers rated maximum power since mid-range and higher frequencies are much easier (power wise) to reproduce.
