The Dayton Audio AMTPRO-4 Air Motion Transformer is designed for professional audio and demanding high-fidelity applications in which high SPL demands combine with the need for detailed reproduction and musical finesse. Highlights Folded Kapton ribbon diaphragm delivers clean, detailed, and highly dynamic output Open back design permits dipole or chamber loading Pro-level output and ruggedness for PA boxes, studio monitors, or high-efficiency home playback Product DetailsDayton 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.
