THIEL Audio’s Jim Thiel Dies


James Edward Thiel 1947-2009

Jim Thiel co-founded THIEL Audio Products of Lexington, KY in 1976, and the company has grown to become one of the most respected manufacturers of loudspeakers in the world. Jim’s passion for music and his interest in electronics can both be traced back to childhood, when he began a lifelong love affair with the piano and also began to build and repair radios and other electronic gear. His academic background in physics and mathematics along with his naturally creative and inquisitive nature led him to pioneer the principle of time and phase accuracy in loudspeaker design. Over the last three decades, Jim Thiel’s speakers have received countless awards from the most prestigious audio publications worldwide, highlighted by Stereophile Magazine having adorned the THIEL CS3.6 as one of the Hot 100 — a group of the most important and influential audiophile components of all time.

“Not only was Jim Thiel a supremely talented and inventive speaker engineer, he was one of high-end audio’s true gentlemen, a gentle man. Had we not been divided by the gulf between reviewer and manufacturer, I would have been proud to have counted Jim Thiel as a friend.”

John Atkinson, Editor, Stereophile Magazine

“The industry has lost a legend. Jim was a brilliant engineer, a sound scientist, a rock of reason and a genuinely decent human being. I will always remember visiting THIEL in Kentucky and seeing first hand Jim’s passion for quality in speaker design and construction and his love of great sound.”

Gary Shapiro, President and CEO of the Consumer Electronics Association (CEA)

When THIEL would host their dealers for training events in Lexington, many remarked that their favorite moments were spent with Jim in his lab, where he would detail his complex work in friendly and digestible language. Jim was known to listen thoughtfully and challenge gracefully, and he garnered a deep level of respect and affection from those who worked at his company. His employees remarked that he was so genuine–he was always fair, kind and reasonable. Jim was a man of science, possessing a profound respect for individuality and personal freedoms.

“Anyone who dealt with Jim Thiel had to admire his integrity, his firm dedication to real-world engineering, and his equal concern that the end result sound as much like live music as possible. He was truly dedicated to advancing the state of the art in loudspeakers, and he made steady breakthroughs during his career without ever losing a sense of quiet modesty and being unwilling to listen to comments and criticism. Virtually every new design he created marked a further step forward in his personal approach to the absolute sound, and it is a real tribute to him that his last major design–the Thiel C3.7–was not only his best speaker yet, but is one of the most outstanding speakers ever made. Jim will be deeply missed for his qualities as a person, his integrity, and his constant search to perfect his designs. He exemplified all the best in the high end.”

Anthony Cordesman, The Absolute Sound
