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 Caernarvon loudspeakers

Time Compensated Dual Concentric Loudspeaker System

Superb stereo sound  has always been a feature of the Tannoy Dual Concentric Loudspeaker. Now the latest Time Compensated Dual Concentric System take another step closer to the real thing

Designed to bring the advantages of the new Dual Concentric System to smaller living areas, the Caernarvon uses a 254 mm (10") version of the Dual Concentric in a compact Floor standing enclosure. The Two-Speakers-in-One" Dual Concentric unit provides a single axis for the generation of both high and low frequency sounds. The complementary Time Compensated crossover produces a single sound source at one point on that axis.

The Caernarvon Dual Concentric therefore, eliminates time delay distortion created by more conventional loudspeakers. A much improved stereo image results, which - due to the wider dispersion of the Dual Concentric - is more accurate over a wider area.

 

 

Careful design and tuning of the Caernarvon cabinet ensures accurate reproduction of lower frequencies to give realistic generation of bass fundamentals. The overall dimensions, however, are small enough to obtain the best acoustic ; match with even quite compact rooms.

The Caernarvon is rigidly constructed from lock - mitred high density particle board, with cross-bracing and bitumen damping of internal panels to increase strength and reduce resonance.

All outer surfaces are veneered in real walnut, and the front baffle has an original cork finish, so that the Caernarvon looks as good with the grille removed. A specially woven Oatmeal cloth is used on the grille, which is removable in three parts.

Removing the centre section of the grille gives access to the high frequency response controls, which can shape the acoustic output of the Caernarvon to suit your particular room characteristics.
