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.

Tannoy Albury SL105 Surrey Speakers

The Tannoy Dual Concentric principle has long been recognised as one of the great technological breakthroughs in loudspeaker design,

Leading musicians use Tannoy Dual Concentric loudspeakers in their live performances  and many recording and broadcast studios rely on the Tannoy Dual Concentric to monitor the quality of their output. This same "monitor" standard of sound reproduction is available to yoy in the Surrey Series of Time Compensated Dual Concentric Loudspeakers from Tannoy.

Look behind the grille of any Surrey Series loudspeaker and you will see what appears to be a single drive unit. This is in fact the "2-speakers-in-One" Dual Concentric drive unit.

Operating through the centre of the bass cone, and sharing the same chassis frame, is a compression high frequency driver. These two separate drive units provide a single axis for the production of sound at all frequencies. The audio signal is supplied  to each drive unit by a time compensated crossover, that aligns both high and low  frequency sound sources towards a single point on that axis.

Each Tannoy Surrey Series loudspeakers is, therefore, a virtual Sound source. This is widely accepted as the "ideal" loudspeaker type, as all Frequencies that make up the sound you hear will originate from the same point in Space and thus maintain their correct time relationships. The music is clearer and More natural, because the real harmonics and dynamics of instruments and voices remain , while your sound image of the original performance is sharper and more convincing.

If everybody listened to music with an average audio system in an average sized room, then we would make just one type of Dual Concentric loudspeaker. Your System and listening environment, however, are as individual as you; so Tannoy Offers you the choice of five Dual Concentric loudspeakers in the Surrey Series

You can choose from the compact Esher, which uses the smallest ever Tannoy Dual Concentric with an 8" bass cone; or two larger shelf or stand Models, the Darking and the Chartsey. Should you have the space for larger free-Standing loudspeakers, then the top-of-the-range Bradley and Albury models will Give you really outstanding performance. There is a loudspeaker in the Tannoy

Surrey Series that will match your system and enable you to enjoy all the sound Advantages of the Tannoy Dual Concentric System
