Gale, I auditioned one of these when they first came out 4 or 5 years ago. I was intrigued whether a cone speaker (the 4.5) would sound smoother than a horn. It did, but the aluminum cones makes me nervous from a re-coning standpoint, so I ultimately passed on it. But it was very smooth sounding, lacking that raspy top end that never strikes me as musical for my use.
