Dayton Audio AMT Mini-8 Air Motion Transformer Tweeter 8 Ohm

The Dayton Audio AMT Mini-8 model features a round housing and compact AMT element, for wide dispersion that easily replaces dome tweeters in retrofit or new design applications. The AMT Mini-8 is small enough to be used in compact satellite speakers, or installed in the center of a mid-woofer to create a full-bandwidth coaxial driver, or implemented in other ways — including line arrays. The sealed rear chamber design of the AMT Mini-8 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.

Note: This tweeter was designed for press-fit mounting, but now includes a 2.25″ diameter faceplate for front baffle mounting.
