That said I ahve heard the Tannoy drivers and like many they have their strengths and weaknesses. KEF's Uni-Q driver is worse. Some fullrange drivers (a la Jordan's JX92, Fostex 103, 108, 127, 167, 168, WR/FR125, Lowthers, Tangband, Supravox, Veravox, etc.. might be better at reproducing the fullrange) but that is topic for another forum. |
Navin there is no loudspeaker without limitation in this world. Everyone is looking for best possible compromise to attain coherent full range sound. Not to forget every loudspeaker sounds fantastic in isolation.
Full range drivers are different story. They have limitations to play loud until they are used in horn loaded enclosures even after that they lack dynamic abilities and suit a particular genre of music. All of them have roll off in HF.
If you need dynamic loudspeaker it has to be with multiple driver arrangement minimum 2 -way.
Tannoy has a long history of more than 80 years in manufacturing loudspeakers founded back in 1920's and made legendary driver "Dual Concentric" in early 1930's. Lot of founder of big names have come from Tannoy only eg. founder of KEF used to work for Tannoy, there is a long list to follow.
Tannoy has not done "simple task of shoving the tweeter down the midbass / woofer throat". There is lot of research and development which has gone in development of Dual Concentric driver over the period of 70 years. Over these years lot of manufacturers has tried the idea of shoving the tweeter down the midbass/ woofer throat but have failed miserably. KEF UNI-Q is one of them.
Recently in late 90's Tannoy developed supertweeter to extend the HF response for high definition mediums, which does made huge difference to the sound but was bullied in "Audiophile" world. Following to its production other manufacturers either started manufacturing supertweeters (KEF) while others extended the response of their tweeters (B&W).
Coming to the point Dual Concentric is a phase coherent driver in which tweeter and midbass are time aligned physically unlike other conventional loudspeakers where complex crossovers and funny cabinets with sloping baffles are used to time align the drivers.
Tannoy Dual Concentrics run on simple straight forward first order / second order crossovers arrangements because of properietory driver arrangement.
As far as moving woofer cone disturbing the HF is concerned. It is totally non existant as it is taken care by properietory waveguide system Tulip / Pepper Pot in Dual Concentric Drivers.
Listen to Tannoy Dual Concentric. It will be hard for anyone to move back to conventional Multi Way loudspeaker.
Its been 10 years I have been using Tannoy loudspeakers. Today no matter how advance and expensive the multi driver loudspeaker is, it is difficult for me to listen to it for long period as i can locate the drivers. Its not me it is same with every Tannoy Dual Concentric users.
I have listened to large variety of speakers B&W, Martin Logan, Magnepan, Aerial Acoustics, Avalon Acoustics, Dynaudio, Krell, Avantgarde, Sonus Faber, Wilson Audio, Canton, Acoustic Energy, JBL, KEF, Egglestonworks, Celestion, Miller & Kreisel, NHT, Paradigm etc.
I will choose Tannoy over these as my personal liking.
Tannoy is a very big name, people in India does not realise.
But ask Parsi's what Tannoy is all about he will tell you. I still remember I was at Mumbai AV revolution, an 80 year old parsi gentleman who could barely warlk came along with his grandson to Tannoy demo room. He said I have come here just to see Tannoys. Before leaving he said "I need repair kit / new drivers for my 40 year old Tannoy Speakers so that I can pass them to my Grandson". Guess what he got the driver for his 40 year old Tannoy loudspeaker from the factory.
Saying that Tannoy still supports the loudspeakers manufactured back in 1920's with spares.
Very Few Credits :
Tannoy Professional has been serving in Bellagio Hotel Las Vegas, U.S. Navy Ships, London House of Commons etc and in coming Dubai Burj (the cost of Tannoy speakers to be used in this project is more than Tannoys own annual turnover)
Tannoy Studio is being used legendary Bernie Grundman, Movies like Terminator 2 - True Lies - Titanic were mastered using Tannoys, Eve Anna Manley of Manley Labs uses Tannoy SRM 10's Monitors for testing her amplifiers and personally uses Tannoy Westminister Royal), Luciano Pavarotti uses Tannoy Reference Westminster Royal for personal listening.
These lists are literally endless.
The name Tannoy is much more than just another loudspeaker manufacturer.
