The 2inch AMT tweeter utilizes a pleated diaphragm driven by a printed circuit, compressing air for highly efficient wave propagation. Structurally, it offers superior heat dissipation, reduced moving mass, and higher sensitivity compared to conventional dome tweeters. Sonically, it delivers exceptional clarity, detailed high-frequency extension, and minimal distortion with fast transient response. This tweeter is designed for Hi-fi audio system.
