Epifani DIST cabs impedance switch

For curiosity sake: how does the impedance switching in Epi DIST series work?

I am to curious to take this as an answer

I don't think googling a product page the OP had already found on their own is answering OP's question.

The link mentions dual voice coil drivers, so presumably switches between different impedance voice coils, I cynically think about sensitivity and wonder if you actually get any more volume running an s/s amp into the 4 ohm set instead of the 8 ohm ones. The epifani web page on;y gives a single sensitivity figure, but it would be interesting to know whether the sensitivity is in fact identical for the two configurations.

This was my guess too. I hope someone looked inside

The Hartke HyDrive HD112 also employs a dual voice coil that allows for 4 or 8 ohms selection.
If I recall correctly, the first generation Accugroove cabinets (not what's offered today) also had impedance selection, and it was generally flamed because the company had a clumsy explanation as to how it works.

You would either have to have two coils or have a single coil with a tap half-way, so for 4-ohm, you're just using half of the 8-ohm coil.

which would significantly impact sensitivity on one position or the other.

The only way to get this setup to work in the way customers would envision is to add some oil from a snake.
