Description
The Dayton Audio AMT2-4 Air Motion Transformer tweeter brings clarity, transient speed, and musical finesse to your design. The tweeters round faceplate flush mounts into baffles easily, and groundbreaking AMT technology enables high output from such a compact driver.
The Dayton Audio AMT2-4 features a round faceplate and compact AMT element, for wide dispersion and overall performance that easily replace dome tweeters in retrofit or new design applications. The sealed rear chamber design of the AMT2-4 eliminates the need for a separate internal chamber in the loudspeaker enclosure.
Dayton Audio AMT (Air Motion Transformer) tweeters use groundbreaking transducer technology from the original ESS/Heil Air Motion Transformer to provide ultra-clean, detailed, and dynamic treble output. The pleated ribbon diaphragm of an AMT provides a large acoustic radiating area condensed into a compact chassis, for extremely high output and improved power handling.
Features
- Advanced Air Motion Transformer design "squeezes" air molecules instead of shoving or crushing them
- Folded Kapton ribbon diaphragm delivers clean, detailed, and highly dynamic output
- Round metal faceplate provides easy mounting and a classic look
- Powerful, lightweight neodymium magnet structure for low distortion and high efficiency
- Sonically similar to the best metal ribbon and planar tweeters
