In this case, though, the tweeter was specifically developed for the purpose, and uses a metal dome fabricated from aluminium alloy and carbon fibre, driven by a coil within a rare-earth magnet assembly.
So much for the traditional Tannoy dual-concentric drivers - what of the Supertweeter? The concept is not a new one other manufacturers have adopted similar approaches in the past, although not always achieving such an extreme bandwidth.
The proximity of the bass/mid-range cone to the treble driver acts to extend the effective length and flaring of the horn, which improves upon the efficiency of the design and helps to provide greater headroom at high frequencies. Generous amplifier power ensures natural dynamics, and sophisticated analogue signal processing guarantees accurate time alignment and a linear response.Īs with other dual-concentric designs, the central treble driver interfaces to the outside world through a hyperbolic short horn, referred to as a Tulip Waveguide.
