Tannoy - A short history

In the early days of broadcasting radio sets needed both low and high voltage DC power that had to be supplied by batteries.
The lead acid batteries used in the radio sets of the time needed regular recharging.

In London, in 1926, Guy R. Fountain perfected a new type of electrical rectifier with the aim of designing a charger more suitable for
use in the house. His rectifier consisted of two dissimilar metals held in a special electrolyte solution. One metal was Tantalum and
the other an alloy of Lead. So successful was this invention that Guy Fountain founded a British Company called Tannoy (a contraction
of the words ‘Tantalum’ and ‘Alloy’). Tannoy soon became internationally known and highly regarded in all aspects of sound reproduction.

Moving coil loudspeakers with DC energised magnets began Tannoy’s continued success in the field of loudspeaker technology.
A discrete two-way loudspeaker system followed in 1933 and shortly after a range of microphones and loudspeakers capable of high
power handling.

Tannoy has always been at the front of the communications revolution, developing its own equipment and production technology.
The company built a fund of knowledge and experience, that has proved invaluable in the development of loudspeakers for a truly wide
range of applications. The now famous Tannoy Dual Concentric principle was created and developed under Guy Fountain’s direction
around 1950. It is highly regarded by music enthusiasts, and recording and broadcast studios because of its unique properties in
faithfully reproducing sound to an unusually high quality standard.

Guy Fountain retired from the company in 1974 but the Tannoy company continues his philosophy dedicated to the accurate and
realistic reproduction of music for both enthusiasts and professionals around the world.

The Tannoy Research and Development unit has further refined the innovative Dual Concentric principle. Using the latest design
and material technologies, with sophisticated circuit techniques in crossover design, Tannoy has produced a loudspeaker system with
superb reproductive capabilities and exceptionally wide dynamic range.

Tannoy is now part of the TG Group, whose goal is to design, produce and distribute the best engineered, most recognised and
respected brands of audio products in the world.

Unpacking instructions

Unfasten the bottom of the carton. Fold the end leaves out of the way and remove the packing tray to reveal the plinth and bottom
of the loudspeaker cabinet. Locate and remove the accessories pack from the carton. Turn the carton and loudspeaker over so that the
cabinet now stands on the floor inside the carton. Lift the carton upwards to reveal the loudspeaker.

Check all packing material and inspect the carton for signs of external damage. If there is evidence of excessive mishandling in transit,
resulting in damage to the loudspeaker, inform the carrier and supplier immediately. Always keep the packing in such circumstances for
subsequent examination.

Tannoy strongly suggests that you store the complete packaging set for possible future use.

Initial positioning

Locate the loudspeakers so that the favourite listening position is approximately 15 degrees from the axes of the cabinets. The axes of
both cabinets should intersect at a point slightly in front of the listening position. Remember that the proximity of the loudspeakers
to walls and corners will affect the sound. Some experimentation will probably be needed to fine-tune the stereo image depth and low
frequency sound quality. Close-to-wall positions and room corners more so have the effect of increasing very low frequency sound energy.
Reflective adjacent walls may upset the stereo image by causing unwanted reflections.

These loudspeakers are designed to be used at least 1 m from any sidewall or reflective surface and at least 0.5 m away from a rear wall.
Only in this position will their exceptional stereo image depth capabilities be realised.

Holes are provided in the base of the speakers for down-spikes that give maximum stability, these special floor coupling spikes are
provided in the accessory pack and these should be screwed into the base of the loudspeakers, taking care not to over-tighten them.
When the loudspeaker is installed in its upright position, the spikes should pass between the weave of your carpet to contact the floor beneath.
Adjust the spikes for maximum stability.

For polished wooden floors, nylon self-levelling ‘ball and cup’ feet are provided

The Dual Concentric drive unit

One of the unique advantages of the Tannoy Dual Concentric™ principle is that the low and high frequency sound radiation is
generated on the same axis. The high frequency unit is mounted behind, and concentrically with the low frequency unit. High
frequency sound radiates from the centre of the low frequency unit through a carefully designed exponential horn. Low and
high frequencies are therefore fully integrated at source. It is this feature that gives the Dual Concentric driver such unique sound
reproduction qualities.

There are other significant benefits. The high frequency unit does not obstruct the low frequency unit in any way (a unique feature
when compared with other so called coaxial systems). Polar dispersion of sound is symmetrical in both horizontal and vertical planes.
By careful crossover network design the virtual acoustic sources of the high and low frequency units form a virtual point source.
Therefore the total sound appears to emanate from a single point source located slightly behind the drive unit. This means that the
loudspeakers, when fed from a high quality stereo source, can recreate a full and accurate stereo image.
