"Air Motion" because the Adamsfamiliar to me from the German company's strong showing at pro-audio showsfeature modern versions of the Oskar Heil-designed "Air Motion Transformer" higher-frequency drive-units that a brief period of popularity in the 1970s. This uses a corrugated aluminum-foil diaphragm that moves somewhat like an accordian bellows, alternately squeezing and stretching the air between the folds. Adam, who is entering the North American high-end audio market, was proudly showing its top-model Tensor series at SSI, but I was also impressed by the active A5 shown in the photo, which crosses the AMT tweeter over to a moving-coil woofer at 2.2kHz and costs just $900/pair. With the $600 Sub 7 active woofer also shown in the photo, a pair of Adam A5s would make the basis for an affordable high-quality system.
The rest of the show system comprised a Resolution Audio digital front end and DNM amplification and cables.
