Product Details

Dayton Audio AMT2-4 Air Motion Transformer Tweeter 4 Ohm

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.

Dayton Audio AMT2-4 Air Motion Transformer Tweeter 4 Ohm
Dayton Audio AMT2-4 Air Motion Transformer Tweeter 4 Ohm is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from Replace tweeters in $55 BIC DV62si with these !I was looking for surround/center channels to work with my classic Heil AMT 1B speakers with the Great Heil AMT ribbons tweeters. I couldn't find anything affordable. It turns out that the Dayton AMT2-4 is a drop in replacement for the tweeters in the Bic. The 3,500 Hz crossover works well and physically they fit perfectly. You can only use three screws to mount the new tweeters due to the cutout at the bottom of the exiting tweeter opening. But this is not problem. Works just as we'll with the matching DV center channel.

Rated 5 out of 5 by from Great Fit for the unit.These were purchased to replace a set of paper-cone tweeters in a small Polk Bookshelf speakers, that had sustained damage to the cone surface, while the woofer was replaced by a Hi-Vi magnesium unit, and the total package is louder and more dynamic then before, as well as a more exhibited sense of space, that is critical for emotional impact. $50.00 pair, now sounds like $500.00 the pair, great product for the Hiel Air Motion Transformer.

Wanting to upgrade cerwin vega Mx400 HORN 8ohm with the 4 ohm heil units. good idea or problem?

Asked by: Keinai bo
These are a lot of potential issues with doing this. The impedance difference will cause a shift in the crossover point and without knowing that crossover point its hard to say what it will do to the sound. The sensitivities are likely going to be different as well. Replacing the originals with these will require a complete crossover redesign.

Wonder if anyone out there who has used this driver or any other AMT drivers can help me compare.  Pretty familiar with Goldwood GT510 1 in soft dome tweeter.  How does this driver compare in terms of detail, imaging.  Worth about 6 times the price?

Asked by: 1957Teddy
You will notice an enormous improvement in detail, imaging, timbral accuracy, and dynamics. Whether that improvement is worth the higher price is a value judgment every speaker designer must make, but I think you'll be impressed with the AMT2.
