20 electrostatic history in the late 1800’s, any loudspeaker was considered exotic. Today, most of us take the wonders of sound reproduction for granted. It was 1880 before thomas edison had invented the first phonograph. This was a horn-loaded diaphragm that was excited by a playback stylus. In 189...
