Vifa XT25SC90-04 1" Dual Ring Radiator Tweeter
This tweeter will work with crossover frequency 1300 Hz 18db/oktava? What tweeters can work on this crossover?
Unfortunately no, this tweeter will not work crossed over that low. Generally you want to double the Fs to find a safe crossover point at 18 dB/octave. We only have a few options that are safe this low and one would be the Dayton RS28A-4.

Does this tweeter have a faraday shorting ring?
Being the way it is constructed, I doubt it.

1st order high pass @ 3kHz safe?
Hello,Seeing as these have a REALLY low Fs, I was wondering if it was safe to just add a cap to these at 3kHz to protect them. I'm going to be using them in a car audio application to improve the high frequency response. They'll be on-axis as well.Could I cross these even lower or do I have to cross them higher by using just a cap? Thanks.
Crossing these over at 3Khz @ 6db/oct will be fine, but personally, I would go up slightly to 3600hz. it will put the tweeter 12db down at 1800hz and 18db down at 900hz (right above the FS). Additionally check the sensitivity of the drivers you will be combining these with. If the current speakers are less sensitive, you system will sound a little "bright" - if your current speakers are more sensitive, you system will sound a little "smooth"... .02 from an old IASCA SQ guy...
