- Extremely emotional musical presentation
The AMT-68 is engineered to reveal subtle musical information with impressive realism while maintaining a smooth and natural listening character.
Key Features
Air Motion Transformer Technology
At the heart of the AMT-68 is its Air Motion Transformer diaphragm design. Unlike traditional dome tweeters that move air in a piston-like motion, the AMT structure moves air through a folded diaphragm, allowing faster transient response and improved efficiency.
This results in:
- Enhanced transparency
- Greater micro-detail retrieval
- Improved dynamic response
- More open and spacious presentation
KAPTON Diaphragm Construction
The AMT-68 utilizes a lightweight KAPTON diaphragm designed for stability, precision, and consistency at high frequencies. This contributes to the tweeter’s ability to reproduce complex musical information with remarkable accuracy.
Aluminum Foil Conductive Element
The use of aluminum foil conductors helps minimize moving mass, supporting the fast and responsive character that defines AMT technology.
Extended High-Frequency Performance
With frequency extension reaching far beyond the traditional audible range, the AMT-68 is capable of reproducing harmonics and ambient information with exceptional openness and realism.
Performance Highlights
One of the defining characteristics of the AMT-68 is its ability to combine technical performance with musical enjoyment.
High frequencies are reproduced with excellent transparency and detail, yet remain natural and emotionally engaging. Instruments retain their texture and realism, while vocals benefit from improved openness and harmonic richness.
The result is a sound signature that feels spacious, effortless, and highly immersive.
Designed for Advanced Sound Quality Systems
The AMT-68 is intended for active DSP systems and high-end sound quality installations where precise crossover control and system tuning are available.
To achieve optimal performance, Rebec recommends a minimum crossover point of 4.5kHz or higher.
When properly integrated into a well-designed system, the AMT-68 can deliver an exceptional level of transparency, air, and realism that highlights the advantages of Air Motion Transformer technology.
Application
The Rebec AMT-68 is ideal for high-end DSP-controlled systems, custom sound quality installations, and enthusiasts seeking a unique alternative to conventional dome tweeters.
Its combination of transparency, speed, and musicality makes it particularly attractive for listeners who value realism, openness, and emotional engagement in their music.
Summary
The Rebec AMT-68 is a premium Air Motion Transformer tweeter engineered to deliver exceptional transparency, openness, and musical expression. Featuring a KAPTON diaphragm, aluminum foil conductive element, and advanced AMT technology, it combines remarkable detail, fast transient response, and natural tonal balance to create a truly immersive high-frequency listening experience.
