This is the story of a real handmade American original. Of three music-loving friends, bursting with new ideas and scientific know-how, and fresh from the hallowed halls of Johns Hopkins University. It’s the story of a world-spanning industry just beginning to find its first audience. And it’s the story of Polk. In the beginning, there was Matt Polk, George Klopfer and Sandy Gross. They popped out of college in the early seventies with top-shelf physics and mechanical engineering degrees. They knew about stuff like The Haas Effect, and how Phase Distortion Synthesis affected audio signals, and at least three definitions of the word “amplitude.” But all they really wanted to do was listen to music at home.
