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.

Jamo D 830 loudspeakers

Jamo Concert bookshelf loudspeakers

In the development of this loudspeaker series Jamo have given priority to  obtaining

A neutral and natural sound balance, so that he sound is reproduced with the exact same tonal characteristics as the original material. A natural benefit of this is that these loudspeakers are able to reproduce all forms of music, speech etc., without adding any sort of "colour" to the sound.

Having started out with such an ambitious goal, an obvious requirement is to avoid any sort of compromise in the entire selection of materials - from terminals to cables, drivers and cabinets.

In the actual developing phase we have therefore carried out listening tests of countless components before making the final selection. Jamo have also tested innumerable combinations of amplifiers, CD players and cables with all types of music and speech in order to ensure construction of an entirely unique loudspeaker series to give you optimum performance in all circumstances.

Tweeter

The tweeter used was chosen because of its musical and ultraa-precise reproduction capabilities. This has been achieved partly by using a special Sonotex diaphragm, the result of a process where the textile diaphragm is coated four times to achieve the optimum combination of rigidity and internal damping.

Woofer/Midrange unit

In the D8 series Jamo wanted the important midrange area to be handled by a single unit, partly to achieve optimum phase characteristics. However, this makes high demands on the unit used, as it must be able to reproduce a wide frequency spectrum and thus be able to endure high loads.
