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 700 L.E. speakers


The original Mission 700 was a landmark in the history of loudspeaker design, such was the acclaim it received and the success it achieved. In fact it is common knowledge that before the 700, budget loudspeakers were simply "boom-boxes". Now, with benefit of many years of research and refinement, Mission are able to introduce a unique, sophisticated, and high technology bookshelf system - the 700 Leading Edge. Advanced technology has been used to develop an exceptional 7 inch bass - mid drive unit. Shaped pole piece and an ultra-fine voice-coil gap combine with a rigid high mass cone, to produce an unusually extended bass response. Refined cone geometry and damping, with progressive hyperbolic suspension affords both high power handling, and inherently low coloration. This bass-mid unit is complemented by a ferrofluid cooled 19 mm dome tweeter. The system is capable of handling musical material with exceptional dynamic range, including digital masters, and remains linear even at modest power levels-unlike many nonlinear systems which, at low level, sound little better than a transistor radio.

The unusual inverted drive unit geometry, first designed by Henry Azima in the Mission 700, goes some way towards equalising the distance from the acoustic centres of the drive units to the ears of the normally seated listener. The effect of such a design is that at the crossover frequency the radiation lobe is directed up towards the listener rather than down to the floor.
The refinement goes one step further in the use of a time delayed baffle board resulting in dramatically better acoustic phase linearity, with substantial improvements in realism, dynamic, and stereo imagery. The baffle board itself is precision injection moulded in polypropylene reinforced with natural composite materials. This combines with Mission's multi-fold technique for cabinet construction to ensure phenomenal transient attack.
The Leading Edge is a high performance system offering a rare combination of accuracy, low coloration, extended dynamic range, and high power handling.
