What is stereo?

There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

THIEL Model 02 (1976)

THIEL Audio approaches speaker system design with the intention of providing the discriminating listener with musically accurate loudspeakers that incorporate a broad range of important performance characteristics. Our emphasis on total performance requires attention not only to musical qualities, but also to such characteristics as high efficiency, rellabillity and cost-effectiveness. The Thiel model 02 loudspeaker is a two way ported design that provides smooth, natural reproduction and good bass response in an efficient bookshelf system.


Smoothness and balance are the most critical factors for natural sounding reproduction of music. The Model 02 has a smooth response and is accurately balanced, resulting in very detailed and natural sound. Accurate bass response is an important musical characteristic that is often not achieved in speakers in this price class. The bass response of the Model 02 is clean and tight, extending flat to 45 Hz without boom or distortion.

Efficiency,although not directly audible, is very important for realistic reproduction of the dynamic range of music. Dynamic range capability without amplifier overload is facilitated by the high efficiency of the Model 02. The combination of natural reproduction, good bass response and high efficiency distinguishes the Model 02 as an exceptional value in its price class.


Relatively small diameter drivers are employed for excellent transient response, very broad dispersion and uniform power response. The woofer is a 6½ inch unit for accurate reproduction of midrange musical detail. A high crossover is thus permitted, which is above the ear's most critical range. The bass frequencies are produced by a ported system with a fourth order Butterworth tuning to 45 Hz. The extended bass response is the result of the small woofer with a long throw voice coil in conjunction with the port loading. The tweeter is a one inch cloth dome exhibiting excellent transient and dispersion characteristic extending to 20,000 Hz.

The cabinet is hand-crafted with geniune hardwood venners with a natural, lacquered finish. This finish is designed to show off the inherent beauty of the specially selected cabined woods; Black Walnut, Brazilian Rosewood or White Oak.

Quality is carefully maintained throughout manufacture. Each driver and crossover is individually tested before final installation. After completion the system is carefully inspected and again tested to asure that it is performing to specifications. The confidence that we have in its quality and dependability is reflected in our 5 year warranty.
