AirBlade Speaker - wow

So I found these also, I guess there are several manufactures that utilize the AMT in their design.

https://legacyaudio.com/products/view/aeris I like these!

@kingdeezie Thank you for that. It was interesting and I like that speaker design.

Jim Salk at Salk Sound made an active speaker using these Arya products and Purifi woofers. 

The overall sound was apparently excellent but very cost prohibitive. You can read the posted thread but the general impression I interpret from Jim is that they are not worth the premium over using the Satori Beryllium driver on his SS9.5s.

 

@sc2  I owned the ESS AMT-1B speakers for a long time as I used them in a 2nd home up until about 4 years ago when I sold them.  I re-foamed the 12" woofers a couple times and replaced the 12" radiators.  Always loved the sound of the Heil AMT.  You're right, the Heil AMT's are fast so you'd want a fast sub like a REL. The crossover frequency of the AMT 1B speakers is 800Hz, so you'd need a sub capable of good response a bit beyond 800 Hz and possibly a crossover assuming you can't feed the Heil AMT's full frequency. You can find Heil AMT's in good shape on eBay for under $500, so for someone with a REL or other fast sub, they could prototype a rig for about $600 including purchasing the Heil AMT's and a DIY crossover. If the results are good, then add a 2nd sub and xover and you're all set.

Thanks @cycles2 ,Those look cool! I wonder if they put an active sub in there, if it would improve... I would think the AMT would be fast and the low end slow to keep up...

The Airblades are a variation of the Heil AMT (Air Motion Transformer) design.  In the '70's I owned a pair of ESS AMT-1B speakers that used a Heil AMT speaker as the midrange and tweeter.  It also had a 12" woofer and 12" passive radiator. Check out the below link. I paid $700 back in the '70's. The Heil AMT sounded great. The cabinet for the woofer and radiator was the weak link.

 

One thing for sure, not only fails WAF, also fails HAF and any other AF. Those are clinically fugly on a new scale.

@sc2 , thanks for the links, it's always interesting to perhaps get a peek at the next great thing.  Later on we get to make the call on whether or not to take a pair home with any true believers...;)
Granted. the presenter seem definitely out of his element, and the demo came off not blowing my socks anywhere.  As to where and how much?  Please stand by, I guess...

There's something about the physics of it that bug me.  That it rivals in some ways the complexity of a MBL which may have promise the demo didn't exhibit.
Oh, well....watch the stars, see how they run...🤷‍♂️

I think I'll keep playing about with my Heils' and diy Walsh drivers...but, thanks again. *S* 

Not a 'bot, still....

But what does it sound like?

How much are these ? I don’t see any specs on these or if they are in the U.S.

@carlsbad  Any of them impress you enough to share?

The completely flat impedance and phase graph because of no inductor is impressive. Also the customizable radiation pattern and the ability to handle high power.  "We haven't burned a single driver so far....".

 

This seems like a more slick version of MCTech speakers shown at the last couple CAFs.
