AMT2838

Introducing our Air Motion Transformer AMT2838, meticulously engineered to elevate the auditory experience in high-fidelity audio products. Designed to be the pinnacle of sound reproduction, the AMT2838 delivers ultra-clean, detailed, and well-defined mid to high-frequency sound, setting a new standard in audio excellence.

Crafted with precision manufacturing, stringent quality control processes, and advanced glue dispensing techniques, our AMT2838 is engineered for long-term durability and unwavering performance, ensuring that the product in your hands is synonymous with reliability and stability.

The AMT2838’s magnetic system provides a robust B field to the formed diaphragm, enhancing its overall performance and contributing to its exceptional sound output. The diaphragm assembly is a marvel in engineering, featuring polyimide foils encapsulating aluminum conductive film. Our innovative high-precision forming technique ensures that each diaphragm is crafted with a high degree of repeatability, enhancing unit-to-unit consistency and delivering stability, resulting in unparalleled audio performance.

The AMT2838X4-541A is a 28x38 mm neodymium Air Motion Transformer (AMT) tweeter rated at 10 W AES (20 W continuous) into a nominal 4-ohm load. Sensitivity is 96 dB (1 W/1 m), measured in the operating band. The AMT operating principle uses a folded film diaphragm driven by neodymium magnets to move air with very low moving mass and minimal excursion, resulting in extremely low harmonic distortion and excellent transient accuracy across the high-frequency operating range. The integrated waveguide controls dispersion and provides consistent acoustic loading. Nominal free-air resonance is 2,200 Hz, defining the lower mechanical limit of the driver.

The frequency response rises from approximately 1 kHz, reaching the operating plateau of 94-96 dB in the 4-5 kHz region and remaining flat to beyond 20 kHz. Unlike dome tweeters, the AMT impedance curve shows a very flat response across the audio band (approximately 4 ohms, with minimal variation), reflecting the fundamentally different electrodynamic mechanism. The smooth high-frequency response and very low harmonic distortion above the crossover frequency are characteristic of the AMT topology and distinguish this driver from equivalent dome and compression driver designs.

The driver is rated for 10 W AES into 4 ohms and is suited for high-fidelity and studio monitor applications. A crossover frequency of 2,500-4,000 Hz (18-24 dB/octave high-pass) is recommended, set above the lower mechanical limit to maintain excursion protection and ensure the driver operates in its optimal planar-motion regime. The flat 4-ohm impedance simplifies crossover network design. Good to use with 5-8-inch woofers such as 5FHWX4-380, 8FHWX4-382, 8FHWX4-088, or 8FHMX4-091 in 2-way hi-fi bookshelf, studio monitor, or audiophile-grade loudspeaker designs.

The AMT2838X4-541A is suited for premium hi-fi 2-way systems, studio reference monitors, and audiophile bookshelf loudspeakers where the AMT technology's extremely low harmonic distortion, smooth high-frequency response, excellent transient accuracy, and compact integrated waveguide provide a high-performance alternative to dome and compression driver designs.
