What you are looking for is built into most decent HT receivers, and that is called filters.  Any subwoofer for even a HTIB has a built in crossover/filter which filters out any sound over a user controllable crossover point.  Typically that is around 120hz and higher, only allowing frequencies lower than 120 hz to pass through to the speakers.  The same is true for the high frequencies.  It all depends on the type of front/center/rear speakers you have.  For instance, I have floor standing speakers for my fronts, which are perfectly capable of the full spectrum of audio.  So I leave those set to "Full Range".  However my center and rear speakers are bookshelf style speakers which can't handle the low frequencies like towers or subs can.  So those are crossed over at around 120hz and higher.  These controls are typically in the software of the receiver and would need to be set by the user.  Unless you purchase a high end receiver.  They often come with a microphone that plugs into the receiver and have a mode for automatic EQ setup.  
 
I hope I have answered most of your questions.  If I have only created more questions.  Post them here, and we will try to help you figure them out.
