Are you ready to try an Air Motion Transformer Tweeter?

To my knowledge, the Beyma and AC are clear material

Thanks, hadn't spotted that. I guess they use an alternative to amber coloured DuPont kapton.

Is the Dayton amt2-4 the same spec as the similar looking Airborne? The Dayton spec sheet has less of a bump at 15khz.

No- they are very different AMT's.

AC's are black

Hi Carl,

Did you also compare to the AC AST2560 too? There's a BIG difference in price between the Mundorf and the AST2560.

No, I didn't compare. Just went with the Mundorf's based on my B652 AIR experience. I chose the smaller AMT for my Intimates because it was a perfect drop in flush fit to my BB's.

Where is this still available?

If you're asking about the Intimates, click on the top link in my signature line. If you are referring to the B652 AIR mod, click on this link....http://techtalk.parts-express.com/fo...highlight=b652

Hi Carl,

Thanks for the reply. I've been comparing AMT's and Mundorf was on my list. One more question; I see you're using a 2.3K crossover. The spec sheet lists 2.8K recommended 2nd order. Any problems crossing the 19CM 1.1 that low?

Thanks!

I was confident I could cross that low due to the 100W rating. Visit my web page and look at the Omni mic distortion test results.

Hi Carl,

Distortion measurements look very good. I was just curious if you ran into any difficulty with the Mundorf 19CM 1.1 AMT pushing the crossover point down to 2.3K.

Thanks for your response.

We'll see how good a job I did this coming weekend. The CT Audio Society is holding its annual BBQ and speaker shoot out. The Intimates will be up against the likes of KEF's LS-50's and other very good speakers in a blind shootout that will feature a novel twist. Speakers will first be judged in mono (single speaker) and then in Stereo. We'll see if that difference makes any difference. :-)
