How to Build Your Own Speakers: Step-by-Step DIY Tech. The electronic components inside a loudspeaker are actually quite simple. The drivers and crossovers pictured here are available in a $369 kit. (Photograph by Chris Eckert) It was back in 1924 that a couple of researchers from General Electric, Chester Rice and Edward Kellogg, patented what remains the basic design for virtually all the world's loudspeakers.
In the 84 years since, engineers and enthusiasts have invested a lot of thought and energy in the refinement of Rice and Kellogg's concept, creating a valuable knowledge base for the do-it-yourself crowd. I should know--I recently built the speakers pictured on these pages, and in the process I learned quite a bit about the art and science of a good speaker. At its core a loudspeaker is a surprisingly simple device. Hardcore speaker hobbyists take delight in figuring all this out for themselves, designing and building the crossovers and enclosures from scratch to see what comes out.
