How to make Electrostatic Loudspeakers (ESLs)

updated November 2006


Mark Rehorst

In the 10 years since I last updated my ESL pages, a lot has changed and I have learned a little more about some new materials and sources so its about time for an update.  The good news is it is now easier than ever to make your own ESLs.  Many more people have made their own speakers and created web pages to show how, so there is now more help than ever before available to the nascent speaker builder.

This page does not have specific plans for how to make a particular size or performance ESL.  Here I try to present you with enough information and ideas that you will be able to decide for yourself how to make speakers that meet your requirements.

Have a look around, and feel free to email me with any questions, comments, or suggestions related to my web site or ESLs.
