In Loud Talker, author John Jenkins examines the early history of loudspeakers and headphones, including a close look at the many oddball devices that came along the way. Also included is a color photo gallery of some of the most beautiful and unusual vintage loudspeakers ever made! Excellent source documents and over 70 photographs and illustrations (most in color) help tell the story that lead from early experiments in electricity and sound to the development of modern loudspeakers.
