Based on info from the one guy I know of who actually bought an instrument to measure the bias V on his Sound Labs, right at the panels, you are absolutely correct; I think he measured 7 to 8kV!!!
Just to clarify, because I am not sure what you meant, the mylar on the Bev panels is conductive and not subjected to a bias V at all. The mylar is instead driven by the dd amplifier in concert with the stators. Don't ask me how or why this works as well as it does; I am still thinking about it. But I think this has a lot to do with the fact that my speakers are still working, all 3 individual panels in both spkrs, after 30 years. The Bevs panels are quite reliable.
