Guess who has the lowest distortion...

Distortion VS applied voltage is what you want to look at. Who has the lowest distortions across the boarder, really.

Wouldn't it be better to test at given spl rather than applied voltage if you are trying to compare tweeters? Obviously it would all depend on how the tweeters are used. While some might be better on the low end others that are bad on the low end might be better in the high end.

Guess who has the lowest distortion with the same voltage applied actively crossed over @ 1500hz 24/dB per
octave...

Drivers do not increase nonlinear with increased voltage proportionally.

Spock would make a horrible speaker designer.

But you cannot accurately compare them against each other with a constant voltage either. You still need to see the distortion at a specified spl to compare them to each other. The best way to compare would be to take a series of tests at different spl levels.

Yes.
No disagreement there.

Never mind, the post was supposed to be fun, I just measure similar to the way voice coil magazine
does it. But I can see this forum is only about telling people they are doing things incorrectly, when
there are many ways of doing things effectively. If I was you guys I would say let's see the graphs!
Some people refuse to learn.

Was post 5 aimed at xmax then or am i misunderstanding something?

Get to it!

I wanna see some graphs. That way I can have some real evidence that you're doing things incorrectly.😉 Seriously, let's see 'em. I'm guessing the SEAS waveguide tweeter has the lowest distortion with the described crossover.

Graphs please.
Thank you.

Let's see the graphs! I'm guessing the satoris followed by the dxt, transducer lab, Scan.

All else being equal, the TLabs might have a bit more 2nd order HD at the same voltage as the others, but it is also higher sensitivity. If these were measured at the same level of output, then I feel the TLabs would edge out the others.

At the same voltage? The DXT will have lower HD at the bottom of the spectrum due to its response characteristics. Since HD increases with decreasing FR, I'm betting the DXT has the lowest as the test was conducted.
