" Audio Innovations was prototyping a “Third Audio” amplfier, using the then extremely novel 845 bright-emitter triode in push-pull. This amp was shown at hi-fi shows in 1990, but never released commercially."
I wonder what happened to that?

I have a pair of what look to be mint Coral 8A-7 16Ohmm 8W drivers if of any interest to anyone. They badged Eagle but look exactly the same as the Coral ones.
Unless really valuable happy to donate for nothing with costs of postage paid to the forum.

OK… Yes. It is a car.
The Bugatti Tourbillon.
It has an unusual sound system - instead of using loudspeakers, the Tourbillon uses piezoelectric elements that vibrate the car’s carbon-fibre tub, using it as a diaphragm.
This effectively makes the entire chassis a loudspeaker. A separate element is attached to the roof of the car, using it as a subwoofer.
Unusual loudspeaker solutions aren’t new in cars: Mercedes used the entire front firewall of the 2013 SL as a loudspeaker. (They also used more conventional speakers.)
