Yes, it was a very "bad" generalization.
In the context of GoodSoundClub, I will say that amplification removes the absolute necessity for matching of efficiency within a couple of dB. Whether or not the tweeter needs 115dB output depends on what range that we are talking about. For someone crossing over at 1.5 - 2K, yes a great deal of "headroom" is needed (I will question 115dB however). If they cross over at 10-13K I believe the world looks much different. The question at UHF is more about integration than efficiency. The transient nature of UHF may need incredible peaks which is far different that the more sustained nature of sound as we go down the frequency scale.
I can envision a higher powered amplifier to preserve that peak nature......... 115dB UHF is not the question for me however.
