Pentagonally shaped enclosure. The 615 model heads the SIXES series of Tannoy and were designed and manufactured in the mid 1990s. The high performance, low diffraction, low coloration that is provided by the unique cabinet design is exploited to the best advantage by the use of 8" dual concentric drive units with its moulded cone and its 30KHz "tulip" waveguide tweeter. This is augmented by an 8" Bass unit driver and an 8" Passive Radiator (called MTPC: Mass Tuned Passive Cone by Tannoy). Tannoy was founded in 1926. A Drive unit that can reproduce accurately the entire audio signal simply does not exist. Therefore multiple drive unit designs are adopted as a compromise. The problem here is that the treble and bass portions of a sound signal (a saxophone for example), are reproduced from different places on a conventional speaker design. With Tannoy's patented single point sound source design, the high freq driver shares the same chassis as the bass driver and the whole audio range is perceived as coming from the same point in space.....like the ideal drive unit, producing almost tactile and palpable stereo images of tremendous stability. Unique to the 615 is Tannoy's "Tulip" Waveguide tweeter, Molded Cone Piston technology, Bi-wiring technology and Differential Material technology.
