A good tweeter to match 5" SB Acoustics Magnesium Woofers

[dlr]

I've never seen a comparison of the a model of a driver's directivity (usually the model assumes a rigid piston and not a cone or dome) vs the actual directivity of a rigid driver before breakup, so I don' know how useful a model would be. Is there data in the public domain making some comparisons?

It's good for generalizations, especially for crossover comparisons, but can't go beyond that for any of the software I've used which admittedly is limited. Maybe SoundEasy can do a better job since it has built-in diffraction options. I don't know if Bohdan added driver directionality into it.

Yes, please do show us. Seriously I'd like to see it.

This is a 8.2uF cap with .35uH followed by a 6 and .33 ohm resistor because it was what I had laying
around. (I did not have a 6.2 but please trust me the .13 ohms will not make a difference)
Yes the choke is unwound to .35 don't make me prove it, please.

If you think this test is flawed that is fine tell me how you would like me to change it
or do it yourself.

I was really hoping I was wrong but I knew what I was hearing when I have tried to
do similar designs in the past. We are here to learn aren't we?

Note the distortion is a little higher when I am speaking.

A crossover of 2kHz where the tweeter Fs is 1350Hz, doesn't that go against everything you believe in? The tweeter is only ~12dB down at Fs, yikes!

The SE filter optimizer sure knows how to pick the right values ;)

Amazing what a 2 ohm shunt can do. But yeah you are right it is too low for my taste
even with a serious impedance "swamp".

I bet if PETT still had the tag fuction there would be some doozies in this thread

What a lol train. Please xmax stop embarrassing yourself, go back to the LCD Cookbook and learn the basics, driver attenuation start around page 175. Distortion is not affected by a series resistor

"The distortion measurements shown are inaccurate and flawed.

Obviously these tests are not standardized only to show the distortion can be higher with a series resistor.

Thanks for quoting my first post in this thread again, I'm glad people get to read it again.

Yep, page 175 of the Loudspeaker Design Cookbook, 7th edition.
