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.

Mission 717 loudspeakers

Different designers emphasize different aspects of the speaker characteristics. For example, some speakers offer high efficiency to the detriment of accuracy; others produce smoothness and low coloration but fail to generate adequate sound levels and musical dynamics; many impress on initial listening, but in the long-term produce fatigue and become irritating. At Mission we try not to compromise, and have optimized our designs within the limitations of the current state of technology. The result is a range of loudspeakers capable of reproduction of all forms of sounds accurately with very low distortion, excellent efficiency, and with high power handling potential. The speakers themselves are neutral in that they have no characteristic tonality. They reproduce all types of musical program with maximum fidelity to the original material. Above all, they are capable of attaining without distortion, sound levels with the realism of any live concert.

 

The 717 is a brand new addition to the Mission range. Here, the greatest challenge to our design team was to ensure a significant advance over the 700, which has presented genuine competition to many models costing substantially more.

Mission 717's will now set a completely new standard of quality in their price category and will be one of our most formidable products for the 1980s.

The 717's advanced 210 mm drive unit features a plastiflex treated cone material which is radially reinforced to achieve a combination of lightness, rigidity and sonic opaqueness. The 25 mm soft dome HF unit offers smooth treble response and excellent dispersion.

This high performance system offers a rare combination of accuracy, low coloration, high dynamic range, high efficiency and high power handling. Above all, loudspeakers of this quality will only be fully appreciated after extensive listening tests using a wide variety of musical material. Only then will the discerning listener experience the astonishing realism and depth offered by today's technology at its best.
