Higher sensitivity - more dynamic sound?

Lonemountain- why did you arbitrarily start at 102 db volume for the high efficiency speaker but 86 db for the lower one? The more efficient one can also of course play @ an 86 db level using a small fraction of a watt & thus probably w/ extremely little amp distortion. Both speakers can have the same dynamic range assuming a sufficiently powerful enough amp for the lower efficiency speaker. The high efficiency speaker can achieve it more easily, likely quicker too & w/ much less required power

Assuming the definition of dynamic “range “is the difference between the softest sounds & the loudest ones a speaker is capable of without minimal distortion, then high efficiency speakers don’t necessarily have a greater range. How dynamic they sound, to me, meaning how quickly they can start & stop & thus sound more like live music in this way, is another story. High efficiency speakers w/ reasonable impedances ( not silly low w/multiple drivers connected in parallel), generally horns of some type can sound much more dynamic than low efficiency ones. I’m a believer of this & own & love my Volti Audio Rivals @ a true 98db efficiency. They can image pretty well, pretty detailed, not crazy extended at either frequency extremes but with a good input, sound more like live music than most other speakers I’ve heard at anywhere near their price range. I guess I value true dynamics over etched, hyper detailed “hi fi” sounding speakers. We all have favorites.
