The result was a break through in TL Theory. In its simplest explanation, driving the line at two distinct points overcomes both the damping problem and loss of energy, resulting in a smooth power response from the lowest fundamentals right through to the midrange frequencies.
Avon’s ribbon tweeter design uses an ultra-thin alloy sandwich precisely positioned in a powerful transverse magnetic field, where the ribbon acts as both the voice coil and diaphragm. In this way the whole radiating area is driven directly and responds accurately to the music signal without energy storage or breakup. Together, the direct drive and low mass of the ribbon provide superb musical detailing and transient attack, resolving the harmonic content of the music in a thrilling and natural way.
