Page 4: Tannoy - A Short History
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’... -

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. - Page 6 The cone flare continues the high frequency horn profile to ensure a smooth transition at the crossover point. Low frequency alignment is through the front firing Tannoy Distributed Port System (DPS). The high frequency section The high frequency driver consists of a wide dynamic range compression unit giving superb transient performance with a smooth uncoloured response.

Page 7: Crossover Network
Crossover network During the design of the crossover network the acoustic, mechanical and electrical interactions of the high and low frequency sections have been fully analysed. The crossover is therefore an integral part of the design of the system. The crossover network provides complex equalisation in both amplitude and phase for each section and fully integrates the response at the crossover point. -
Page 8: Connection In Single Wire Mode
Connection in single wire mode (See fig. 2) Connect the pair of link cables supplied in the accessory kit to each loudspeaker terminal panel as shown in the diagram. Ensure that the tightening knob grips the side entry cable terminations firmly. For optimum performance in single wire mode, loudspeaker cable connections from the amplifier should be made to the high frequency (HF) terminals of the loudspeaker: •... -
Page 9: Loudspeaker System Adjustment
Running in Like all loudspeakers, the drive unit in your Tannoy Turnberry 85LE require a while to reach optimum performance, as the stresses in the materials relax - especially in the suspension system. For this reason, it is beneficial to run the system at moderately high levels at normal room temperature, for approximately 24 hours at least to achieve best results. -
