Elberoth2, I was told that they tended to store energy. Perhaps what my dealer meant was that they pass on the signal more efficiently thereby acting as if they were providing more energy on demand. I have noted that they seem to be easier to drive than most speakers and handle loud peaks on complex material extremely well with only my 400xi driving them. Below is a list of the components I have owned:
