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 Westminster TW (1990)

The Westminster TW is a classic horn-loaded design driven by the best in modern Dual Concentric technology. This newly revised loudspeaker is capable of truly outstanding high fidelity reproduction while remaining an imposing and traditional piece of furniture. It is based around the famous 15-inch Tannoy twin-magnet Dual Concentric driver, now with the computer designed Tulip Waveguide for truly extended high frequency performance.

Fine walnut veneers and solid walnut edgings conceal a complex horn-loaded 25 mm particle board cabinet. The horn loading system gives greatly improved efficiency and a large wavefront area approaching that from real instruments. The Westminster TW offers high frequency energy tailoring through high current gold-plated switch blocks with controls for both treble energy and roll-off. Van den Hul wiring is used throughout. Signal handling is via gold-plated terminals with captive link bi-wire/normal wiring and a hard-wired time compensated crossover network. The combination of this closely integrated mid band and single point source guarantees exceptionally realistic stereo imaging.

The Tannoy Westminster TW is effortessly capable of the realistic stereophonic reproduction of truly low frequencies and of the widest dynamic ranges.
