They have an (engine room the size of the Titanic, float about as good too).

Seriously though, these are an end game amp, if you don’t mind the power bill.
Class A- plateau biasing (auto slides up and down to the music signal being played, said to be in Class-A near all the time, no/low music hardly any class-A) so "kind" of environment friendly during quiet passages🙄.

If you can't find one, make sure you look at a stereo Gryphon Antillion Evo, also a Titanic but user adjustable Class-A bias

I don’t believe there’s a speaker made these couldn’t drive without breaking a sweat.
You’ll get a pair if you put out all searches for them, hope you do, get back and let us know.
