As for the lvc, that I don't know.
I was referring to the TABAQ TL enclosure to get the 1 lb stuffing numbers.

The damping is high (1 lb per ft3) and is placed in the upper part of the pipe. The last third of the pipe is not stuffed. The stuffing will attenuate the output from the opening, so I solved this by increasing the volume of the cabinet.

Wrong source, sorry.

So Le is not the same as Lvc...

Is there a way to infer what Lvc is?

I suppose if someone had a Betsy-K and a LCR meter we could figure it out right?

I have tried to find the Lvc for the Betsy k the past, but I have not had any luck. Are you planning on building a zobel network Ron?

Ron's specs seem better. I think the ones I quoted were a one off he had made called the Purple Speaker.

I was thinking of forgoing the zobel, since I can't really calculate the design without knowing the Lvc. I was planning on possibly including a baffle step correction circuit if needed, though with the front-firing ported design of the WIBAQ I'm hoping that will enforce the bass enough the baffle step correction won't be needed.
