In order to dampen resonance peaks at higher frequencies, conventional dome tweeters are injected with fluid to raise their mass, sacrificing transient response time. By contrast, the custom-designed AMT tweeter uses an incredibly thin, folded Kapton^® membrane (<0.01 mm) with an inlayed aluminum circuit functioning as the voice coil, allowing the tweeter to move at the same instant as the electric current. There sulting reactive response time provides marked clarity and superior transient reproduction.
