thiel audio loudspeakers, evaluation




TO HELP US ACHIEVE THE best possible designs, Thiel uses several advanced testing, measuring, and evaluation techniques in the design process. Computer simulations, anechoic testing, and the human ear are all used to ensure thoroughly and completely engineered products.

Superior performance is achieved in part by the use of sophisticated computer aided design techniques.

While computers are poor at making value judgments about how good a speaker sounds, they are extremely valuable for analyzing data and making quick work of many time consuming tasks. THIEL uses computers to simulate driver magnet system designs and electronic crossover circuit designs, and to provide precise information about variables in driver and cabinet construction. Information that would have taken months of experimentation to gather in the past is now rapidly and readily available.

Test and measurement techniques provide feedback to help evaluate the effectiveness of designs.

 Measuring techniques for prototype drivers and speakers allow us to "hear" the results of our efforts to reduce distortion, improve frequency, time, and phase response, and to eliminate unwanted diffraction and cabinet effects.

THIEL speakers and drivers are tested under anechoic (non-reverberant) conditions. Your ear easily distinguishes between the direct sound from the speaker and the reverberant sound reflected from room walls. Since your ear uses only the direct sound to identify the sound's characteristics, only anechoic measurements can indicate the accuracy of the speaker's output.

Listening: The most important test

 By the time a THIEL speaker design is finished, it has been critically evaluated many times in the most important test of all--listening. Because measurements provide only a partial description of performance, listening to the speaker with a wide variety of music and associated components plays a major role in our design process. Changes resulting from evaluations made in our listening room often make the difference between a merely good loudspeaker and a great loudspeaker.
