I couldn't determine how to buy from that site in a manner that I usually use (protection) but I will keep looking.

I'll likely just buy a whole new tweeter.
I am going to attempt to tune this new tweeter to my liking, just more education really.

Also as this tweeter us pretty old given the thread situation so we think the new version will be fine going forward on music if I don't do dumb stunts?

The ASD has 5 more watts power handling but I don't really think I was pushing on this tweeter very hard.
I had it pulled back 12db from the mid/woofer to get the gains set.

Obviously (now) a full power sweep was dumb.

Fellas, Eminence no longer manufactures replacement diaphragms for those tweeters. There may be some still in stock out there or there are some knock-offs. But, I'd just buy a replacement driver - they aren't that expensive.

6 - T39 3012LF
4 - OT12 2512
1 - T24
1 - SLA Pro
2 - XF210

I lied, this neo driver is plenty loud.
The DSP "tune" that was in it was a test tune when I was troubleshooting, I loaded a old tune and it's back!

Really glad I didn't have to set fire to this deal 🤣
Ill retune this when I have time, I need to get the Jack 12 Lite going and accompanying portable sub.

Just keep in mind, the RMS limit of the new NEO tweet is half that of the one that fried. Might want to keep a spare handy, put a DSP limiter module in the signal path and limit voltage to the tweeter to roughly 12 volts, or both.

Great point.
I did some research into how to create the voltage limiters in the SigmaStudio in the past but it goes over my head pretty quick unfortunately.
