DO NOT USE DAVID LUCAS. I know some people personally who have tried his system. He only sells you part of what you need to build a set of speakers. Then you have to buy more from him to complete the project. The cost is high, the build quality is marginal. The customer service is nonexistent. If something craps out on you, you're on your own. David Lucas doesn't return calls, emails, etc. There's more testimony here: http://www.geocities.com/CapeCanaveral/Hall/2239/9041IMAI-DI.htm This site has info on better diy electrostats than david lucas.
