Would this make a suitable bias supply?

for the most part (most of the time) the air in your home is positively charged. This means that a positive supply to your diaphragms will help repel your rooms air and any contaminants in it. This will help to keep your diaphragms cleaner and minimise the amount of potentially conductive build up on your skins that will eventually lead to some bleed from the conductive section of the diaphragm to the frame. As a note all of Jim Strickland's (Acoustat) high voltage supplies were positive. Charge potential has no impact on the panels performance as far as I know. But if you can run positive it is probably woth your while. Regards.

I found that when I used to use a positive voltage on the diaphragm, the copper tape that carried the charge corroded, similar to the way that a car battery's positive terminal corrodes. When I switched to negative charge on the diaphragms, the corrosion ceased to be a problem.

Dust covers are the best solution to keeping drivers clean. They also keep out bugs.

Now you better build an oposite polarity attraction zone, or you will experience the smoked walls look soon with all dust clinging to your walls...

The thing is basicaly a stacked DC voltage doubler....
