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.

Leak 3090 speakers

In Europe, home of some of the world's finest speakers, the Leak 2075 became recognised as a reference. Hardened professionals used this product as a yardstick by which other products were measured.

Enter the 3090 - the yardstick has grown.

The most dramatic improvement is the use of our patented Isodynamic tweeter. This is a flat-field unit, using no conventional coil, cone or dome. Instead, an ultra thin diaphragm with a printed circuit. This is activated by rows of miniature magnets made from Samarium Cobalt - the most powerful magnetic material known to man. The result - a response right up to 26 kHz -3 dB and possibly the best dispersion characteristics of any tweeter around.


 

The midrange is handled by two separate units. The upper midrange unit has holes in it. The precise positioning of these holes was worked out using laser-beam holography, so that delayed resonances are eliminated and this is one of the sweetest midrange units in existence. The lower midrange operates from 500 to 2000 Hz. About 40% of music power occurs in this band and the unit is built to take it - the cone is a sandwich of polystyrene and aluminium for great rigidity.

In the 3090, we have taken special care to make it right for any room, your room. Environmental Controls for Low Mid Range, High Mid Range and the ISO tweeter enable you to find the rigid tonal balance in the listening area and the swivelling upper cabinet means that these directionally sependant frequencies can be tuned to optimal dispersion for your favourite listening position.

Bass frequencies are handled by a 15" woofer,  made out of our unique sandwich of polystyrene and aluminium. The incredible rigidity of this unit means you get perfect piston-movement of the cone for real deep bass of the kind that only transmissionline cabinets can give you.
