Vifa XT25TG30-04 1" Dual Ring Radiator Tweeter
Is there a minimum optimal listening distance for "Ring Radiator Tweeters"?
Do ring tweeters offer less dispersion as apposed to traditional dome tweeters? Would they need to be on axis for a flat response, as the spec sheet response graph suggests to me? Are there better suited tweeter options for building speakers for a small room (or perhaps a car) with a listening distance of just under 2 meters? I have used the Seas 27TFFNCG in a car (close and slightly off axis listening) with good results, but the design here seems different enough for me to ask.
The Vifa ring radiator tweeter is an excellent tweeter as long as you remember its two limitations. You have to use a fairly steep crossover to stop it getting too much power at low frequencies AND it has a very limited off-axis response as you have seen in the graphs. It is a deliberate design feature. There is no optimum distance required to the speakers, rather you need to make sure that where-ever you are positioned, your tweeters are pointing more or less directly at your head and as close to ear height as possible. If you are using the speakers in nearfield (close) you'll need to angle the tweeters in very sharply to your head. You'll have to weight this up but I have to add, as nice as the tweeters are, there are plently of good alternatives out there that give as good or better sound without the off-axis issues of the XT tweeters.

Good woofer match?
I'd like to try this tweet for a simple two-way; anyone have a good recommendation for a woofer? I've done a bunch of car audio and amp projects, but this is my first ground-up home audio build, so I'd prefer to keep crossover complexity to a minimum. I'm probably going to make a few different enclosures to try out, so flexibility for sealed or vented would be a plus. Going for 90% music listening.THANKS!!
This tweeter is very easy to work with, and could blend well with virtually any smaller woofer (say, 8" or smaller) in a two-way system. The simplest crossover in recorded history is a first order (6dB/octave) high pass filter consisting of a single capacitor. This tweeter could be treated thusly with a 5.6µF capacitor, which will provide a gently sloping crossover frequency of about 3500Hz. You'd want to use a woofer that will play up to (but not much beyond) that approximate frequency, and simply leave the woofer unmolested to play up to its full range, at which point it will naturally roll off and let the tweeter take over. Our customer forum is an excellent resource for getting started in this kind of endeavor, here's a link for your convenience:techtalk.parts-express.com

I plan on mounting this tweeter in the same airspace as a pair of woofers. The enclosure will be ported, so the pressure won't be as high, but I'm curious if I should worry about building a small enclosure behind the tweeter to prevent midrange from destroying the tweeter?
You don't need to build an enclosure behind this tweeter. It is sealed.

Is this for one tweeter or a pair?
This is a single tweeter. It has a unique design that uses dual rings, as opposed to a dome or cone as most tweeters use.

Recommendations for Grill in a car for these tweeters?
Would like to install in the upper door of an Acura, but need a good grill cover, any suggestions would be appreciated.
LOCAL CAR STEREO SHOP FOR SOME GRILLS OFF BLOWN UNITS,,, I MADE SOME FROM SANDPAPER CALLED WIRECLOTH, THEY LOOK FACTORY WITH THE BLACK GLOSS COATING, HEMISPHERIC HEAVY WIRE MESH FORMED TO SHAPE IS BEST BUT HARD TO MAKE ,, I NEED TO KNOW MODEL AND YEAR COLOR ETC TO REALLY HELP ALSO THESE ARE NOT CAR TWEETERS AND THE DISPERSION MAY NOT TAKE TO DOOR MOUNTING AND SUN

Can I use these in a energy 22
I know the 22 is a 8 ohm tweeter is there anyway I can adapt this tweeter ?
I would not recommend swapping an 8 ohm for a 4 ohm. Your crossover point will change and updating the tweeter will likely hurt rather than help the sound.
