Dayton Audio AMTPRO-4 Air Motion Transformer Tweeter

The Dayton Audio AMTPRO-4 Air Motion Transformer Tweeter represents a significant leap forward in high-frequency audio reproduction, offering exceptional clarity and efficiency for discerning listeners. This advanced driver is engineered to deliver remarkably detailed and transparent high frequencies, making it an ideal choice for high-fidelity loudspeaker designs, professional studio monitors, and custom audio installations where accuracy and airiness are paramount. Its unique operating principle ensures that every nuance of the recording is rendered with stunning precision.

At the heart of the AMTPRO-4 lies a highly efficient Air Motion Transformer mechanism, which achieves a remarkable sensitivity of 97 dB (SPL 1m/2.83V). This high output capability, combined with a low voice coil inductance of just 0.06 mH, ensures effortless transient response and minimal distortion. The tweeter features a nominal impedance of 4 ohms and a DC resistance of 3.96 ohms, with a resonance frequency (Fs) of 8 Hz and a total Q factor (Qts) of 4.12, indicating its suitability for various crossover designs. With a cut-out diameter of 71.9 mm and a compact depth of 36.1 mm, the AMTPRO-4 is straightforward to integrate into both new builds and upgrade projects, providing a professional-grade solution for achieving the highest levels of sonic performance.
