Found AR3 mid dome inside an AR2a

This AR3 dome midrange was found when I removed the woofers of my AR2a pair of 3/62.
It was mixed in the internal padding of a loudspeaker, probably the waste of an Acoustic Research worker.
In the photos, you can glimpse a piece of the aluminum terminal, not visible, but there is also the other pole, with the cable flush with the output of the dome.
The coil is not interrupted and measures approximately 3.6 ohms.
Acoustic Research always amazes me !!

It looks an awful lot like the diaphragm in a horn driver.  I've heard the speculation on that, yes.

I measured the outside diameter of the coil and is 52 mm. about.

I confirm that the appearance and the foam globs are similar to the 1 3/8 tweeter, also note the fiberglass cylinder contained inside the dome which is double colour: yellow and orange (almost pink).
