I am sort've new to the Home Theater world but trying to learn, so I apologize in advance if this is a dumb question. I recently bought a Pioneer 140 watt receiver. My question is this, if there were 2 sets of speakers that were completely identical except one was 200 watts and the other has 500 watts. Since the receiver is only giving out 140 watts, would there be any difference at all between the 2 speakers? Would one have better sound or be louder? I would appreciate any guidance that I could get.
