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 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.
