The Scottish company TANNOY was founded back in 1926 and today might be the oldest existing manufacturer of loudspeakers worldwide. The most important milestone in the history of TANNOY was the invention of the Dual-Concentric-Driver in the year 1947. Unlike ordinary drive units, the Dual Concentric™ is effectively two drivers properly merged into one, where the high-frequency unit is positioned on the back of the low frequency driver to ensure that they are on the same acoustic axis. With this system, the sound energy is propagated from the same point and delivered through the centre of the low frequency cone – a true point source! The high efficiency, a high power rating, an outstanding clarity in sound and a holographic sound-staging founded the legendary reputation of TANNOY. Today the dual Concentrics are available in different price classes, so that high quality stereo sets and home-cinemas can benefit from the superior qualities of TANNOY.
