Tannoy Autograph Mini


Loudspeaker Prestige Series - pair

Article code: EX-DEMO



    


The Autograph mini is a hugely scaled-down but authentic version of a loudspeaker that was famous throughout the audio world fifty years ago. Reduced to a fraction of the size of the immense and revered original Tannoy Autograph this exquisite replica is the ultimate modern retro audio product. Its diminutive size and accurately detailed finish produce a modern day classic that will embellish the most contemporary surroundings. Remaining true to the cabinet build and finish quality of that yesteryear model, the Autograph Mini naturally incorporates a 4.00” Dual Concentric™ driver - the unique engineering statement that makes this speaker a 'real' Tannoy. Combining wide bandwidth technology to ensure breathtakingly natural midrange and a heavy cast alloy frame and multi fibre paper pulp cone for well defined bass performance, this miniature Dual performs with subtlety, stunning detail and expansive imaging.

Features
A key component of the Autograph Mini is the titanium diaphragm high frequency unit positioned on the same axis as the bass section. Fitted with a neodymium magnet system to deliver a smooth response up to an incredible 54kHz, this key component in the Autograph Mini enhances the loudspeaker’s strikingly true to life performance. Ensuring complete signal path integrity, 99.99% high purity silver cable is used to connect the tweeter to the system’s minimalist crossover network - a thoroughbred audiophile component in itself that includes low loss inductors and specially damped audio grade capacitors. High density birch ply with hardwood veneers and solid hardwood mouldings are utilised in the unique and chic design of the hand finished cabinet. As with its erstwhile and larger predecessor, authentic oatmeal coloured grille cloth is used to conceal the driver and is also inlayed within the angled sides towards the front of the miniature hexagonal cabinet. A high performance loudspeaker designed for the discerning fashion conscious.

Drive units
The unique advantage of the Tannoy Dual Concentric™ principle is that the low and high frequency sound radiation is generated on the same axis. In effect, the Dual is a single chassis comprising two separate drive units properly merged into one, with the high frequency unit mounted in the centre of the pole piece of the low frequency unit. High frequency sound radiates from the centre of the low frequency unit through a carefully designed high frequency exponential horn, either the PepperPot WaveGuide™ or the Tulip WaveGuide™ dependant on the model. It is the fact that the low and high frequencies are therefore fully integrated at source that gives the Tannoy Dual Concentric™ driver such unique sound reproduction qualities. The location of the high frequency unit does not physically obstruct the low frequency unit in any way; a unique feature when compared with industry standard coaxial systems. Polar dispersion of sound is symmetrical in both the horizontal and vertical planes. By careful crossover network design the virtual acoustic sources of the high and low frequency units can be made to occupy the same point on the axis. Therefore the whole 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. The low frequency section of the Dual Concentric™ drive units has exceptional power handling and dynamic range. The low frequency cone piston is produced from selected multi-fibre paper pulp. This is specially treated to absorb internal resonance modes. A treated fabric surround, or rubber surround in the case of Autograph Mini, is designed to correctly terminate the moving cone and provide optimum compliance and linearity at large excursions. The cone piston is driven by a high power motor system, which in selected models uses an Alnico magnet. Alnico is an unusual iron/nickel alloy doped during the melt process with cobalt and aluminium to produce a magnetic material with very special properties. Having a high remanant magnetism and energy product, Alnico magnetises to a high level and retains an unusual degree of magnetisation. Alnico is also an electrical conductor. These properties give the Alnico magnet equipped Dual Concentric™ drivers an exceptionally clean transient response and increased sensitivity. The coil is wound with a special high temperature adhesive system and individually cured to ensure reliable operation at high peak power inputs. The shape of the low frequency cone is arranged to provide optimum dispersion of audio frequencies at both the high and low ends of the spectrum. The cone flare continues the high frequency horn profile to ensure a smooth transition at the crossover point. The high frequency driver consists of a wide dynamic range compression unit giving superb transient performance with a smooth uncoloured response. The compression unit feeds acoustic power through a low compression phase compensating device, either the Tannoy Tulip Waveguide™ or the PepperPot WaveGuide™, to the throat of the acoustic horn formed by the low frequency cone. The low frequency cone profile provides a second waveguide with acoustic impedance transformation to match the high frequency radiation into the listening environment. Either a titanium or aluminium alloy diaphragm, formed by a specially developed process, produces a piston with a very high stiffness to mass ratio. Optimum molecular grain structure gives long-term durability. A low mass precision coil provides the driving force for the diaphragm, energized by a powerful magnet system. A damped acoustic cavity to one side of the diaphragm controls the compression driver response and ensures perfect integration at the crossover point.
