Product Details

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 faceplate for front baffle mounting.

Dayton Audio AMT Mini-8 Air Motion Transformer Tweeter 8 Ohm
Dayton Audio AMT Mini-8 Air Motion Transformer Tweeter 8 Ohm is rated 4.8 out of 5 by 5.
Rated 5 out of 5 by from Nice super tweeterI used this tweeter to fill in the top end of an AMTPRO-4. Using a 1uF cap in series and a 10 Ohm resistor in parallel it matched perfect.

Rated 5 out of 5 by from Fantastic Car TweeterInstalled a pair in my Mercedes door sail mounts using a high quality capacitor in-line. Fit was quick and easy to replace factory tweeters. Used a 4.7 mf 5% Capacitor as a crossover. The sound is super clean and cuts the wind noise without being loud or shrill. The 6db roll-off and large surface area help make a smooth transition with the door speakers while sharpening the mid definition. Cymbals, acoustic guitar and brass instruments sound lifelike and stereo imaging is noticeable. The cleanest and most realistic car tweeter I have ever heard.

Rated 4 out of 5 by from Nice little tweeterI bought this mostly to check out the Air Motion thing on the cheap. I must say, I am impressed. It is very airy and detailed sounding and the larger mounting plate is nicer looking than I was expecting. It has pretty incredible off axis response; a lot like a ribbon. 5db down @ 18K measured 45deg off axis. I didn't take measurements above and below axis, I would expect similar performance as I believe the Air Motion technology is supposed to perform better than ribbons in this regard. They have a limited usable frequency range; above about 4.5K. So as long as your design calls for this they're good to go. Say in a three-way or used with a well behaved 5.25" in a two-way crossed 2nd order minimum.I made a supertweeter out of them crossed at about 10K 2nd order. I may try them with a waveguide in the future to better match the power response of whatever speaker I attach them to.Hard to beat at the price if you keep the limitations in mind.

Rated 5 out of 5 by from SWEET TWEETSInitially I was attracted to the look and form factor as in ease of modifying, being unable to leave anything alone! Upon opening nothing had changed. Excellent build quality! Wow! All cast and heavy. These also happened to be the perfect diameter to upgrade my auto tweeters, and as luck would have it my factory system used an 8 ohm mylar dome as stock. Given the ohm match and delicate nature of a 1/2" coiled mylar, I figured no additional crossover was needed, and these are now singing away wonderfully in my daily driver! Much more clean output and I was able to retain the factory look wiyh na little trimming and adhesive. Definitely worth the cash.

Rated 5 out of 5 by from A spectacularly accurate tiny tweeterI could not resist the temptation to order a pair of these. I have been a long time fan of the Heil design since it was introduced, but could never justify buying the original midrange/tweeter unit (WAY above my audio budget limit). When I received these, I was puzzled at how to build tweeter stands for them, but finally figured out to cut holes in 1/2 inch hardwood plywood slightly smaller than the tweeter diameter, and (with my trusty Dremel tool) carve out the front of the opening to the depth of the tweeter. After inserting the tweeter in the prepared hole, I fastened it in using metal strips attached to the #8 machine screws that extend from the back of the tweeters. I crossed the tweeters over using 6.8 mFd capacitors and an 8 Ohm L-pad for a crossover frequency at about 3500 Hz. Since this is a closed back driver, a simple 2-piece tweeter stand suffices--no box needed.As add-on super tweeters for the Dayton B-652's these are OUTSTANDING, providing 'air' and realism actually better than all but my most favorite (HiVi lower priced RT) ribbon tweeters. In terms of output, these are slightly less efficient than the ribbon tweeters I have tried (including the small and medium sized Beston models), but plenty enough to match the B652s, as well as some slightly more efficient home brew designs I have built lately.My only complaint is the lack of mounting hardware or mounting instructions (not a problem for someone with imagination, scrap wood, and a Dremel tool, but still...not quite up to the usual product support I have previously seen from Dayton Audio).This product definitely belongs on the short list of affordable, super-accurate, relatively inexpensive supertweeters for enhancing commercial speaker systems or home brew designs.

Would like to use these in a vehicle.  What value capacitors would you recommend for a simple 1st or 2nd order crossover?

Asked by: Synrg
I would recommend a 3.3 uF cap for this if you want to go first order. If you want second order, part number 266-474 will work well.

I have a portable speaker build in mind that will probably see lots of bumps/vibrations. How durable are these things, compared to conventional domes etc?

Asked by: davedave
These will hold up as well as any other type tweeter in terms of durability.

I purchase a pair of these AMTs before you offered free face plate. Can I still get a pair of face plates?

Asked by: ScottM
We may be able to work something out if you call our tech department. We do not offer these separately so we will have to try and see if we have any that came back with a defective or damaged product.

Can this be used as a driver in a headphone? Seems like the biggest challenge would be the impedance; headphones tend to be much higher impedance than speakers.

Asked by: ClaytonJ2
Unfortunately this would not make for a very good headphone driver due to its lack of anything below about 5,000 Hz and extreme lack of excursion of any kind.
