Would this make a suitable bias supply?

I found this ion generator kit on eBay

The output looks adjustable. Any reason why this wouldn't work? Buying this as a kit would be very convenient for me..

It looks like it would provide adequate voltage at a safe current level. I'd say it's worth a try.

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.

Hopefully I'll be able to swap the diodes around to chose whichever polarity

looks like a very nice supply. Remember too if your budget is tight that you only need one supply to charge both panels. This does mean that you would have to run a supply wire to each speaker but makes for a 50% cost saving. Let us know how it works out for you and what kind of voltages you can get off of this supply. Regards.

Well I have ordered one so we shall see what happens!

You have to like the side benefits of owning ESLs:

By this, an air-regenerating effect as well as the binding of dust and bacteria will be achieved. A high share of negative air-ions is necessary for general well being: it reduces troubled sleep, aggressiveness, headache, sensitivity to changes in the weather, lack of concentration, etc.

Alright, it arrived today. It took about 20 mins to build and it worked on the first try

Here are some pics:

It seems to work nicely! It certainly hurt when I accidently put my finger across one of the multiplier caps too!

Is that a small blue spark in the second photo?

BTW. When you turn the power source off does it still hold a HV charge?

Looks very neat.

Yes that is indeed a small spark!

As for it retaining HV, it seems to. If I put a screwdriver onto the output after turning it off I get a small click. The capacitors certainly retain a charge as my poor finger found out!
