Imagine an orchestra, a small combo or a single musician playing in front of you. A variety of tones and its harmonics is produced, not to mention the dynamics: from the hissing of a barely touched string to the full sound of a blasting orchestra. All these nuances must be reproduced in your home, in the right tonal balance, by a relatively small enclosure: the loudspeaker.
A real challenge to the engineer dedicated to music. Computer-aided design and knowledge of materials are very useful tools for the designer to melt all relevant parameters together, but attending concerts, tweaking and another extensive listening-session are even more important for the finishing touch to the product.
