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 Royal

The Westminster Royal is Tannoy's crowing achievement. This loudspeaker offers a compound horn-loaded enclosure driven by classic Dual Concentric technology. The Westminster Royal sets the standard for low frequency, dynamics and presence that no other system canmatch. This horn-loadedclassics pushes back the limits of loudspeaker design, while remaining a magnificent and timeless piece of furniture.

Based around the Alcomax 3 version of the famous 15-inch Tannoy Dual Concentric the Westminster Royal now features the benefits of signal handling by gold-plated terminals with bi-wire/passive wiring and a hard-wired time compensated crossover network. The Alcomax 3 magnet system gives the Dual Concentric an exceptional transient response and increased sensitivity.

The substantial 530 litre cabinet - clad in fine walnut veneers with solid walnut edgings - conceals a complex horn loading system that gives greatly increased efficiency and a wavefront area approaching that from real instruments. The Westminster Royal is effortlessly capable of the realistic reproduction of truly low frequencies and the widest dynamic range. Van den Hul wiring is used throughout.

Removal of the wood-framed grille with its specially woven cloth, using the ornate scrolled key, revelas an engraved brass plate behind which are the treble energy and roll-off high current switches. The Tannoy Westminster Royal is one of reproducing the dramatic real-world dynamic range of musical instruments without apparent effort.
