PS - When I say top of the line AMT, I mean the best from Mundorf or Beyma. Definitely not the $30 parts from Parts Express.

Hi Jerry,
I'd have to know a lot more about how you designed the crossovers. DIYaudio's multi-way forum is a better place for that.

As single drivers, I will put up the top of the line AMT's with the best drivers from anywhere else. Smooth, amazing dynamic range and low distortion, not to mention power handling and lack of stored energy. The best are some of the best drivers you can buy.

But, integrating with panel speakers is another matter. You have to match the crossover, phase and dispersion. Trying to use a single drover AMT with a line or panel is going to be very difficult. A better match up would be a line of AMT's , similar in concept to the Infinity RS series.


When I mentioned Linkwitz, he did not do line arrays, but multi-way dipoles. I think in that case a good AMT might have been better than 2 domes.

Best,

Hey @mapman

AMT's are inherently dipoles. You can get them without a rear chamber. I'm actually a little surprised I never saw the late Dr. Linkwitz rely on them for his speaker kits.

Not very new. From the B&W nautilus, to the Focal Sopra line, there have been different approaches taken to minimize the opportunity of the radiated back-wave from influencing the sound.

What I like about the KEF, from what little I've seen, is the motor seems to be more substantial than average from this type of design.

For the ultimate in this, try an open back AMT. :)

Best,
E
