THIEL celebrates 25 years in audio

2002-2003 marks THIEL's 25th year in the audio business. From the very small beginnings in designer and co-owner Jim Thiel's garage in the summer of 1977 with the first THIEL speaker, the model 01, THIEL has grown into one of the leading companies in high performance audio. THIEL now markets a product line of seven loudspeaker models, designed and built in a 40,000 square foot manufacturing facility with over 35 employees, and has enjoyed a history of product and business awards, and critical acclaim from the international press.

Pioneer in loudspeaker time and phase coherence

Jim Thiel's belief that dynamic type loudspeakers have no serious inherent limitations led him to a career of improving dynamic speaker performance. His early design work helped pioneer the principles of time and phase coherence in loudspeakers by the use of time aligned drivers and phase correct crossover networks. These principles contributed to the development and recognition of modern imaging performance. Jim Thiel's designs have incorporated reduced cabinet diffraction with the use of rounded baffles, lowered driver distortion with innovative motor structures, achieved more accurate frequency response with stiffer and specially shaped diaphragms, and reduced unwanted enclosure resonances with heavy cabinet bracing and through the use of cabinets materials like concrete and marble.

High precision meets hand craftsmanship

In these past 25 years, THIEL has evolved from table saws, hand planes, and the outsourcing of drivers, into manufacturing with high precision CNC (Computer Numeric Controlled) machining centers, in-house driver design and building, anechoic chamber measurement, and computer modeling-but still with great deal of hands-on, human involvement every step of the way.


THIEL Audio Products Company is a privately-held engineering-driven organization that performs research, design, and manufacturing of loudspeakers for the highest quality home music and video sound reproduction. Our products incorporate a variety of technological advancements in driver design, acoustical construction techniques, and crossover design. All our work is directed toward one end: to provide the most realistic sound reproduction possible. THIEL manufactures thirteen loudspeaker models, the PowerPoint, PowerPlane, HigherPlane, SW1, SCS3, MCS1, PCS, CS.5, CS1.6, CS2.3, CS3.6, CS6, and CS7.2.
