No sorry it's not about what the spec sheets say.
Open one up and you will discover what it really is.
The exit of the driver ist exactly 1". From there on they just
extended the driver to look like an exquisite old format Alnico thingy.
Got to the DIY Audio forum thread and find my post where I showed
Mr. LeCleach the inerts of my 6681b because he was also trying to correct
me with spec sheet numbers as you did.
He even thought that it was an Alnico driver. Obviously he never opened
his driver further than taking the back cover off.

From the specs on it.
Very similar to the Altec 288, but with BeCu fingers for the suspension.
I have one sitting on the floor next to me.
