I guess that my take on your topic is that you are looking for speakers that will have a greater "impact" in your room over your satellites. It seems you are looking for a high sensitivity speaker that sounds good and doesn't cost you an arm and a leg. A high sensitivity allows a speaker to reproduce music and movies at a higher level with smaller amplifiers, or to put it another way, will demand less from your current amp (that's a broad stroke) to reach the "impact" you are searching for. Head over to your Klipsch dealer to take a look. This is exactly what they design for. SOme people are not fond of the sound, but I beg to differ. I would also suggest looking at the Reference line from Paradigm, which has pretty decent efficiency. These types of speakers, IMHO, are what you are looking for since you will have less of a chance of putting your amp into clipping.
