Have you ever seen a 16 ohm loudspeaker?
I've been interested in and following audio reproduction and equipment
since the 60's.
A lot of theatre speakers were designed for 16 ohms, in order to reduce the
substantial cable losses between the booth and the speakers. You could order
the Altec 288 horn driver, for instance, in anything from 8 to 24 ohms.
Apart from oddities such as panels, ionophones and electrostatics, the
only consumer loudspeakers I've been aware of with an impedance much
above 8ohms were certain models of the LS3/5A which were available as 11
and 15 ohm:

It's not a win for consumer speakers since you're never going to see a very
long cable run in that application, and making the higher impedance windings
is more difficult. Consumer speakers are designed to be cheap.
The LS3/5A was never designed as a consumer speaker, but in the end it sure
wound up being successful in that market.

IIRC there were some JBL D130 speakers that were 16 ohm in the early years.
