The Tannoy's have an exponential compression HF horn that is concentrically mounted behind the bass drive cone and fires through the dust dome of the bass cone.
The HF compression diaphragm is mounted at the rear of the drive unit magnet and is spaced back from the bass cone by one half wavelength at the crossover frequency of 1 Khz.
The HF compression driver is connected out of phase to the bass cone due to it's half wavelength displacement.
All frequencies therefore leave the drive unit in phase and as a point source due to its dual concentric design.
The HF compression driver also has a phase compensating multiple throat for reduced distortion and wide dispersion.
Tannoy dual concentric speakers are used in 80% of the worlds recording studios.
The coaxial/concentric design does make them sound rather
special and lovely.
Don't take my word for it, try a pair and see what you think. I am certain you will not be disappointed.
The flagship model has the whole 15" drive unit mounted in a giant 500 litre compound horn loaded cabinet.
Sadly these are £15,000 per pair.
