Lost in audio
To my mind there are only three speakers on the planet that can be called an LS3/5A; the original 15 Ohm model (various brands), the slightly later 11 Ohm model (various brands) and the current Falcon (which is the first one reborn).
LS3/5a is a particular specification not a specific speaker.
If DH’s design met the spec. then he had created a LS3/5a.
I can't see it any other way. Derek Hughes by building the V2 to spec, made a new ls3/5a. Very carefully, in my opinion.
