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 high performance audio products in the world.
Examine all pieces of packing material and inspect the carton for signs of external damage. If there is evidence of excessive damage to the packaging and resulting 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.
'slow' signals and light current, 'fast' signals. Of course, the loudspeaker must be fitted with two pairs of terminals to take the two sets of cables; your Tannoy loudspeakers are of course equipped for just this type of connection.

Cables High quality audio signals passing from power amplifier to loudspeaker are unusual in their demands on cable. Frequencies from 20Hz to 20kHz (10 octaves or a ratio of 10,000:1) and currents of 80dB dynamic range (again a ratio of 10,000:1) have to coexist. The cable also has to be capable of transmitting peak currents of at least 10 Amp without causing losses greater than 0.001 Amp (10 Amp divided by the ratio 10,000).

™ 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 high frequency exponential horn.
Human hearing relies on the constant nature of the time delay with the intensity to locate natural sounds accurately. A pair of Tannoy Prestige loudspeakers can uniquely reconstruct stereo images and provide excellent localisation of recorded sounds. The Tannoy Dual Concentric™...

Figure 6 shows a developed section through the horn with the rear folded horn straightened out for clarity. This gives an acoustic engineering model that can be used to describe how the compound horn operates. Figure 7 shows the electrical analogue of the acoustic system shown in developed cross section. Mms and Cms represent the moving mass and suspension compliance of the drive unit respectively.
The determination of the cause of failure will be made by Tannoy Ltd or its authorised Distributor or Service Agent based on physical inspection of the failed parts.
