I think today most speaker designers are assuming zero source impedance and

out either side of the nyquist plot to make sure things are stable into a
simple reactive load), and in the end neither of those is necessarily a
good assumption to make.

And of course the speaker isn't even linear and time-invariant.

You could say "voiced to sound best with amplifier type X" at the very least.

Probably fall foul of anti-competition watchdogs, or would be
suspected of dodginess by most consumers.


Generally speaking 8 ohm ratings for amps requiring higher loads than
those rated 4 ohms has worked sufficiently OK for most users since
solid-sate amps became common.
