They can be "rated" too high for a receiver/amp. If you have a receiver pushing 200 watts (let's assume 8 ohms), and a speaker rated at 400 watts (8 ohms...the same impedance), then you will probably blow your speaker. What the speaker rating tells you is the amount of watts you should be sending to the speaker, so as to not cause clipping in the speaker (from a signal not strong enough...it therefore becomes an intermittent signal), or to overwork your amp, which can cause the signal to start distorting, or your amp to overwork itself to a nice, smokey demise. It would be like trying to power a turbine with a trickling creek.
If you're running music from your computer (or cd player or whatever...line level output to your receiver), then your speakers should be rated the same watts for ohms as your receiver's output. If you're running a PA system, then you'll need more juice from the amp than the speakers run at to guarantee you won't fall under the "clipping" level. Just don't exceed the max wattage.
Hope this helps!
