Don't Forget the Loudspeaker - A History of Hemispherical Speakers at Princeton, Plus a DIY Guide

This paper gives a historical overview of the development of alternative sonic display systems at Princeton University; in particular, the design, construction, and use in live performance of a series of spherical and hemispherical speaker systems. We also provide a DIY guide to constructing the latest series of loudspeakers that we are currently using in our research and music making.
