Arya describes the AirBlade as a broadband, low distortion, high power, linear phase and linear impedance driver, that does not become directional towards higher frequencies and from the available info it appears as a quite clever application of the AMT principle with a fully redesigned mechanical infrastructure.
According to the details published, to overcome the limitations of the dynamic driver and other technologies, rather than using a heavy diaphragm with separate voice coil, the AirBlade transducer incorporates light-weight ring-shaped foil elements arranged in layers with conductive aluminum traces directly bonded to them. When an electrical signal is applied, opposite layers of the diaphragm either move towards or away from each other depending on the direction of the signal, thus moving air and creating sound. By using many diaphragm layers the total surface area can be significantly increased. In the AirBlade 180 model, the surface is more than 37 times larger compared to that of a traditional 1-inch tweeter while having similar outer dimensions.
The company says that the diaphragm construction, in which adjacent layers always have opposite current flow, leads to a cancellation of inductive effects making the driver behave almost perfect electrically and acoustically with no significant resonance peaks, while, due to the curved shape of the diaphragm the AirBlade driver radiates equally in all directions and does not become directional as traditional dynamic drivers. Furthermore, the directional characteristic can be tailored to the requirements of the application.
The driver uses aluminum conductive materials, because aluminum is better than any other existing metal when it comes to the conductivity per weight factor. In fact, its conductivity per mass is twice as good as that of copper which is the second best material. If nano science research will -one day- be able to overcome the challenges of producing graphene in reasonable sizes without loosing its promising properties, this also might be an option, Arya states.
During this year's High End Show in Munich, Arya Audio, displayed their AirBlade 180 driver, with a frequency range wider than the 1kHz-20kHz interval, 180° directivity (360° and other versions are available upon request), 4 Ohm purely resistive, linear phase impedance, and a diaphragm surface area of 19200mm2. The driver uses 34 neodymium magnets, wights about 1.4kg and measures 135x76x76 (mm, wxdxh).
