Monacor AIRMT-85 Air Motion Transformer Tweeter.
Air motion transformers (AMT) are a unique type of high-end ribbon tweeter which were developed by German physicist Oskar Heil during his research into the characteristics of the human ear.
Although AMTs are members of the ribbon family, they have a radically different mode of operation: these tweeters feature a specially folded / pleated diaphragm that expands and contracts along its length like a bellows, transforming an electrical signal into air waves and can therefore technically be viewed as a type of sound modulated air pump.The folding of the AMT diaphragm offers a larger active radiating area in the minimum of space.
AMT tweeters have a highly dynamic sound with an excellent transient response, high efficiency and low harmonic distortion.
We recommend a minimum crossover frequency of 2.5kHz / 18db octave.
