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
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
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.
THIEL's 18' tall test chamber tests
frequency response, impedance, distortion,
and phase response.
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.
