The SB Acoustics Satori AT60NC-4 is a high performance AMT (air motion transformer) tweeter with a very flat on-axis frequency response of ±1.5 dB between 3.2kHz-26 kHz; the impedance curve is almost pencil flat - an excellent result.
AMT tweeters are members of the ribbon family but 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 pleating of the AMT diaphragm offers a larger active radiating area in the minimum of space.
