Description

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.

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 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 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 SPL output, wide bandwidth, 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
  • Robust metal faceplate provides secure, stable mounting
  • Powerful, lightweight neodymium magnet structure for low distortion and high efficiency
  • Open back design permits dipole or chamber loading
  • Pro-level output and ruggedness for PA boxes, studio monitors, or high-efficiency home playback
