Overview

Dayton Audio AMTPRO-4 Air Motion Transformer Tweeter 4 Ohm

Dayton Audio's AMTPRO-4 model features an extremely large AMT diaphragm with an open-back design and powerful neodymium magnetic assembly. This combination produces high output and low distortion over a broad frequency range, while handling large amounts of amplifier power.

Perfect for use in PA loudspeakers, large-format studio monitors, custom cinema speakers, or extreme performance hi-fi loudspeakers, the AMTPRO-4 can easily be chamber-loaded or open-baffle loaded as required by a particular dipole application. Thanks to its ability to be crossed over as low as 800 Hz, the AMTPRO-4 driver is a uniquely effective solution for midrange reproduction as well as treble, and can even be used as a wide-bandwidth “mid-tweeter” driver.

Dayton Audio AMT (Air Motion Transformer) tweeters borrow 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 SPL output, wide bandwidth, and improved power handling.
