My claim on high sensitivity-high dynamic with low distortion is what you often counter among very experienced DIY speaker builders. So it’s hearsay, but not of the naive audiophool kind.
Why is it that some speaker designers prefer high sensitivity drivers?
Such claim is very easy to be proved or disproved by measurements. The point is you made that claim as it is something that is proved, not hearsay. If you heard that from "very experienced DIY speaker builders" which also didn't provide any proof that doesn't make it any less hearsay.
