I'm looking to learn about Air Motion Transformer technology

Hey there, I'm listening to some right now.

The potential is high, but not always realized. There are some damn awful sounding AMT speakers.

The one thing they all share is very low stored energy compared to dynamic tweets. However, their frequency response, and power handling can vary a great deal. The $2 Chinese units are not nearly as good as the top of the line European units. 
At the top end, AMT's are as good if not better than any other tweeter tech. At the low, they hurt.

Listen for yourself.
Best,
E

This review includes the highest level Beyma AMT on the market.

I also want to point something out.


The attention we pay to tweeters, and the amount we pay for tweeters, is really out of proportion with the amount of sound that comes out of them, especially in a 3-way speaker, only about 3 ish octaves.


There’s a lot more to a speaker than having a magic tweet, especially in terms of the total energy output.


Of course, being a geek about tech is what this forum is for. :)

Eric...you need to rethink that emphasis on those 3 octaves to also include the CRITICAL harmonics....see the imperfect amp thread..but ya, there are some AMT that are listenable, and antime the ATM is puking out cash, I am all ears...dyslexia or not...

also there is a decent wiki on AMT w links to the 8 patents...and ESS appears ro still manufacture the tweters in various sizes and complete speakers, might be a fun winter project...
