OWNER’ S MANUAL

Estd. 1926

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 high performance audio products in the world.

2 In combining the best of traditional crafts and the latest production and design skills Tannoy presents the Westminster Royal SE

loudspeaker. The Westminster Royal SE embodies the Tannoy philosophy. Cabinets in selected hardwoods are hand finished and

polished to a standard that is unsurpassed.

The Westminster Royal SE offers a compound horn loaded enclosure driven

by classic Dual Concentric™ technology. Based around the Alcomax 3 version

of the famous 15 inch Tannoy Dual Concentric™ the Westminster Royal SE

now features the benefits of signal handling by gold-plated terminals with

bi-wire/normal wiring and a hard wired time compensated crossover network.

This Alcomax 3 magnet system endows the Dual Concentric™ with an

exceptional transient response and increased sensitivity. The massive cabinet

design conceals a complex horn loading system that gives greatly increased

efficiency and a wavefront area approaching the wavefront area from

real instruments.

The Westminster Royal SE is effortlessly capable of the realistic reproduction of truly low frequencies and the widest dynamic range.

Acrolink 99.9999% (6N) high purity copper wiring is used throughout, together with specially selected crossover components, including

Hovland capacitors. High frequency energy can be tailored through high current gold-plated switch blocks with controls for both

treble energy and roll off.

The specially designed twin-roll impregnated fabric surround used on the drive unit's cone, ensures midrange purity combined with

tight, controlled bass.

The Low Frequency Section

Tannoy 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 high frequency 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 can be made to occupy the same

point on the axis. Therefore the total sound appears to emanate from a single point source located slightly behind the drive unit. This

means that a full and accurate stereo image can be recreated by the loudspeakers when fed from a high quality stereo source.

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 multiple phase compensating device to the throat of a solid

steel acoustic horn. This horn provides an acoustic impedance transformation to match the compression unit radiation into the listening

environment.

A magnesium alloy diaphragm formed by a specially developed five-stage process produces a piston with a very high stiffness to mass

ratio. Optimum molecular grain structure gives long term durability. A very low mass precision aluminium coil provides the driving

force for the diaphragm, with fine multistranded copper lead out wires to ensure reliability. A rear damped acoustic cavity controls the

compression driver response and ensures further correct acoustic impedance matching to the horn throat.

The response of the compression horn driver extends a full two octaves below the crossover frequency to eliminate colourations that

can arise through operation over the fundamental resonance region.

The High Frequency Section

An Alcomax 3 high energy magnet provides flux generation for both high frequency and low frequency driving motors. Precision air

gaps contain the magnetic flux surrounding each coil. The high frequency air gap has a unique shunt member to apportion the total

magnetic flux in the correct ratio between low and high frequency units. This gives an optimum acoustic balance. Precision machined,

low carbon steel pole pieces ensure unsaturated operation, linear flux fields and a high heat sinking capability. High power inputs can

therefore be handled with minimum change of impedance due to temperature effects. A very robust, high quality, precision pressure

die-cast chassis locates the whole magnet assembly and positions the moving parts with high accuracy. This provides long term reliability

and yet does not interfere with the acoustic radiation from the individual sections.

The Magnetic Circuit

Alcomax 3 is an unusually high energy permanent magnet. The unusual iron / nickel alloy is doped with cobalt, aluminium and other

rare metals to produce a magnetic material with very special properties. Alcomax 3 has a high remanent magnetism and energy product.

In other words, it magnetises to a high level and retains that unusual degree of magnetisation. Alcomax 3 is also an electrical conduction.

These properties give the Dual Concentric™ drive unit using an Alcomax 3 magnet an exceptionally clean transient response and

increased sensitivity.

Alcomax Magnet

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. All components are

high precision, low-loss and thermally stable. A unique shunt element technique controls the motional impedance of the drive units.

All components in the crossover network are hard wired to eliminate unwanted metal-to-metal contact and ensure freedom from

vibration. The components are laid out to minimise inter component coupling and are placed well away from the driver magnetic field.

Specially selected components of the highest quality are used, such as Hovland polypropelene capacitors, non inductive thick film

resistors with extensive heat sinking, and very low loss laminated iron core inductors. Wiring is by Acrolink (99.9999% purity) copper,

having a large crystal structure and stable atomic arrangement.

High current switch blocks with gold-plated screw terminals permit user adjustment of high frequency sound radiation to suit differing

listening environments.

The complementary design of crossover and drive units means that the loudspeaker system as a whole behaves as a minimum phase

system over the audio band and therefore the acoustic sources of the high and low frequency sections are aligned in time and space to

ensure accurate reproduction of stereo images.

The Crossover Network

A Note on Auditory Perception

Our hearing mechanism locates natural sound sources with great accuracy by using the naturally occurring phase differences (or arrival

times) at middle frequencies, and intensity differences at higher frequencies, between each of our ears. Naturally occurring sounds pass

through the air to the ears at constant speed (345 metres/second or 1132 feet/second). All frequencies travel at the same speed and

therefore a frequency independent time delay is associated with the distances involved. (The familiar time delay between a flash of

lightning and the associated clap of thunder is an example).

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™ principle ensures that the source of sound at high frequencies is on the same axis as the source of sound at low frequencies.

The careful design of crossover network complements the drive unit to provide a coincident sound source at frequencies where the

human ear derives phase information for localisation. The loudspeaker system exhibits a time delay response that is in essence independent

of reproduced frequencies. In addition, the amplitude (or intensity) response is linear, smooth and consistent. This provides the correct

intensity information to recreate the original sound stage.

UNITED STATES HOUSE OF REPS

June 1st, 2001

Audio Manager for the House of Representatives, Al Lakomyj, provided the specifications for loudspeaker design. In November of last year, a comparison among four competing loudspeaker products was held in Washington, D.C. The preferred speaker for the floor of the House was from Tannoy.

The loudspeaker that provided the sound quality was the Tannoy CPA5 / i5 AW, but the House had very specific requirements for size and aesthetics. Using the 5" ICT™ drive unit from the CPA5 / i5 AW in custom enclosures was the solution.

Tannoy custom-designed and manufactured 415 enclosures with 5" ICT™ Point Source drivers for the installation and supplied 22 raw 5" ICT™ drivers as replacements for existing enclosures. Clear speech articulation, excellent forward gain, and wide frequency response characterize these compact units. Specially reinforced grille covers protect the loudspeakers, which are situated under the chairs of each member.

“We were turned on to the job on November 30 and we prepared samples within 24 hours,” says TGI-Tannoy’s, Business and Product Development Manager, Larry Howard. Final approvals were completed within days and all the units were shipped by December 16th. “That's a two week turn-around for a custom design and complete product delivery,” says Howard. “Everyone at TGI-Tannoy pitched in to make this happen.”

System designer, Will Parry, of Signal Perfection Limited, agreed: “Tannoy did a spectacular job in delivering the product under an extremely tight deadline.”

The Chamber of the United States House of Representatives is the largest room in the Capitol, used for daily sessions of the House and occasional Joint Sessions and Joint Meetings of the House and Senate. The House first occupied this Chamber on December 16, 1857, moving from its previous location now known as Statuary Hall. Today the room appears as it was when renovated between 1949 and 1951.

TRAVELLER'S TRAIL

July 7th, 2005

Taking the travels of the Arabian explorer as its theme, the Ibn Battuta mall in Dubai is a celebration of 15th Century world cultures. Richard Lawn, from the magazine Pro Audio Middle East, explains the installed audio system.

As the Sheikh Zayed Road heads south towards Abu Dhabi from Dubai, passing the countless cranes raising new high-rise structures around Dubai Internet City, the building projects become ever more opulent. Among them, the Emirates Mall will attempt to entice visitors from 50° of summer heat to its indoor ski slope, while the nearby man-made Palm Island and World coast resorts play host rich and famous celebrities from around the world. It is in this area that the latest shopping mall has just opened its doors to the public.

Themed to mark the travels of 15th Century Arabian explorer Ibn Battuta, the mall’s six courts reflect the most influential cultures he visited, providing visitors a glimpse into the past. Born in Tangiers, Morocco in 1394, Ibn Battuta left his home to increase his understanding of the world that surrounded him, covering 75,000 miles over 30 years- hence, the Andalusia, Tunisia, Persia, Egypt, India and China courts that represent significant stages of his journey. Impressive though his voyages of exploration are, he would surely be equally astounded at the scale, speed and quality of the construction that has taken place in honouring of his name. Exploring the 1.3km complex, it is hard to imagine that foundations were sunk just two years ago, and that the entire interior took a total of eight months to complete.

PMK was appointed the A/V consultant for the project and, from the onset, fully understood the client’s requirements in installing a state-of-the-art A/V system, which would both educate and advertise to the mall’s audience. Following a lengthy technical and commercial evaluation, PMK and the mall owner (Nakheel Properties) appointed local installer Promedia Systems to handle the contract on their behalf.

What Graham Lawton won’t confess to are the severe handicaps that PMK and Promedia Systems were handed by the interior designer company MTE. As in most architecturally-stunning developments, the mall’s audio systems were to be heard but not seen. And, with the exception of China Court, most of the ceilings in the six malls are 20m 30m in height and are too high for traditional ceiling speakers to be installed. The Persian domed court and Tunisian skyline ceilings in particular are works of art, and were never going to be a discussion topic for interior designer and A/V consultant.

Luckily, solutions were to hand. Tannoy was asked to supply more than 600 in-wall iW6 dual-concentric loudspeakers, which have subsequently been installed at regular intervals throughout the mall at heights of 2m to 3m. Each loudspeaker has been carefully orientated to minimise reflections from the shop frontage on the opposite wall. It’s a bitter pill for Tannoy to swallow, but JW MacLean was contracted to design 600 custom grilles to completely conceal the speakers from view. The exception to the rule is in China Court, where a full-scale Junk provides the focal point under a majestic 25m ceiling. Here, 30 Tannoy CMS12TDC 12-inch ceiling speakers provide sound reinforcement as Mr Lawton explains: ‘We weren’t allowed to put speakers into the walls here.’
The five A/V control rooms dispersed around the mall host a large Mediamatrix system and a total of 60 Crown CTs600 and CTs1200 amplifiers, all of which are networked with USP3 iQ cards so that they can be managed from a control room PC or via a laptop, using any of the floor boxes that have a network point. Promedia Systems has amassed a great deal of experience in setting up control rooms with the 17 42U-high racks required to accommodate the equipment being assembled and tested at its offices before broken down and transported to the site for re-assembly. ‘This saved us a lot of time and is standard procedure,’ confirms Mr Lawton. ‘If you’ve followed the schematic drawings correctly and work closely enough with the consultants and other on-site contractors, then you’re not going to run into any unnecessary problems.’

The Mediamatrix system’s primary function is to provide audio routing with each control room containing a number of 8i audio input and 16o audio output bridges, sharing a cable feed with the Crestron Control and Crown iQ Control to the loudspeakers. The main control room can provide a blend of feeds from an Alcorn Mcbride DVM4 HD, DVD, VHS, MP3, CD and satellite entertainment to the plasma screens and loudspeakers. The networked amplifiers are programmed and timed to the Crestron control panel and can be placed in stand-by mode when not in use, while a Wohler 2A unit monitors anything coming through the Mediamatix network in the control room. Crown CT600 amplifiers provide amplification for the Tannoy iW6 loudspeakers using a 70V line system, which tap in at 30W per loudspeaker, Tannoy transformers were used throughout the installation.

No two days in the life of a mall will be the same, despite the systematic programming that has been inputted to the system. The various malls can host live entertainment at various points where 60 floor panels offer local microphone, line inputs/output and video tie lines and control system network connections, all of which are selectable via the Crestron system. At the other end of the scale, voice evacuation and a fire alarm interface can be monitored centrally – and muted, should a false alarm have been activated – on a zone-by-zone basis. The facilities manager ultimately holds the keys to the entire network through various passwords on the Crestron control panel. If a child goes missing in the mall, a message can be paged to a particular section or to the entire mall depending on the level of alert. Commercially, the A/V system will pay for itself rapidly as Dubai-based Octopus Media is successfully selling advertising space to retailers anxious in enticing shoppers into their particular outlets. If they are not selling advertising time, shoppers are being taught 15th Century Tunisian customs or listening to background music. The A/V system is in continuous use while the mall’s doors are open, and reliability is, as ever, fundamental, so the control rooms really are the nerve centres of the mall.

As the final commissioning takes place, the PMK and Promedia teams are equalising every area individually channel by channel using the Crown iQ Control. ‘The system that has been installed is very flexible,’ Mr Lawton enthuses. On site, tasks were obviously harder, as there were so many contractors on site trying to perform their various tasks that inevitably, many got in each others’ way, and in some instances, we had to start installing when some tasks hadn’t been completed.’

The smell of paint and adhesives were clearly evident in many parts, even after the mall had opened but the Dubai spirit to fulfil the tasks at all costs is strong. ‘I left the site one evening and this area was a wasteland of sand and rubble,’ Mr Lawton recalls. ‘When I returned the next day, it had been transformed into a vast driveway entrance with lined palm trees and lawns. The work-rate and the ambition to get things done here is truly amazing.’
Then again, so is the power of the consumers entering the malls and parting with ever-increasing sums of cash, which in turn is financing the work that has taken place here. However, the dilemmas still remain. Do you opt for a latte in Tunisia, Persia or China? Choices, choices…

I notice that the Genesis 1.1 speakers shown above have multiple drivers. I'm surprised at this for audiophiles. Surely it has always been understood that you can only approach truly accurate sound with one point of sound generation, hence concentric drivers. As soon as you have more than one location of sound generation you get standing wave patterns around the speakers. I suppose that they would work if you were in exactly the correct position relative to the loudspeaker cabinets.
