The tweeter has been moved forward for better time alignment and a shallower but more flared waveguide is said to give better high-frequency directivity. Both mid/bass and treble drivers now use a single shared magnet and a special waveguide integrating a donut-shaped (Torus) tweeter diaphragm and bullet-shaped (Ogive) phase plug. Indeed, this year has seen one of its most radical redesigns, with a new Omnimagnet motor and Torus Ogive Waveguide. The driver has been refined over the years. This brings great phase coherence and better off-axis response too, making the speaker image far more accurate. A Tannoy dual concentric driver, however, will produce all the noteвЂ™s spectral components from a single place at precisely the same time. Think of a violin playing a single note a standard speaker will have different parts of this (including its harmonics) coming from two orВ more points in space at the same time. Whereas normal speakers fire sound out at you from different places on the front baffle, TannoyвЂ™s driver produces it from the same place. It soon found its way into hi-fi speakers, when Tannoy made a monitor for Decca recording studios. This was not soldВ in cabinets, but as research tools for testing microphones, due to the exceptionally flat frequency response. Its first dual concentric design вЂ“ the Monitor Black of 1946 вЂ“ was a coaxial speaker combining mid/bass and treble units in one drive unit. Still, because the concept is so old there has been plenty of time to refine it, and Tannoy came up with its own solution nearly 70 years ago. Moving coil drive units in a wooden box are the most common and simplest type to produce, but arguably the most flawed.

We all know what a good speaker should do, but how to do it is another matter altogether вЂ“ there are many different ways of attempting this. Vive la Revolution! Tannoy's XT 6F newly re-engineered dual concentric floorstanding loudspeaker
