Vifa XT25TG30-04 1" Dual Ring Radiator Tweeter

This superb transducer features a patented dual concentric diaphragm and a unique wave guide center plug which provide an excellent on- and off-axis response. The XT25-type tweeter is acclaimed for its very natural sound with an extremely smooth frequency response that extends well beyond the human hearing range. The dual chamber design and absence of ferrofluid results in a low resonance frequency.

Rated 5 out of 5 by from One of the best tweeter you can buy for under $200Hello, I've been an audiophile for 25 years and have heard sold and heard all kinds of speakers. I can say that I think this tweeter is one if the most natural, open and resolving tweeters I've heard. I've put them in two pairs of speakers I own / built and I would never even consider using anything else for under the $200 price range. They really are amazing. The speaker pictured is with the Dayton 6" reference woofer crossed over at 3K (12db per octive) and they fill my 18 X 15 room with pinpoint imaging and SPL with no sence of strain from my 125 wpc amplifier.

Rated 5 out of 5 by from Exact replacementThese tweeters were an exact replacement for myBlue Sky SAT 6.5 speakers, shipped quick, work great.For anyone replacing older Vifa's with the newer model, be aware that they changed the position of the terminals slightly,and some cabinets will require using a round wood file/raspand cutting 2 notches to clear the new terminals. Other than that, a perfect replacement.

Rated 5 out of 5 by from Dual ringed wonderI needed a tweeter that would cross over low to an 8 inch bass unit but sound clean and extended. With a 2nd order X/O at 1.85 khz the roll off is smooth allowing easy integration and a flat response through X/O.More importantly the design sounds fresh and open with a natural sense of presence - who could ask for more?

Rated 2 out of 5 by from For advanced speakers designers only.Poor off axis responsePoor low frequency responseVery fragile and easily damagedExcellent high frequency detailPoor off axis response - Probably the worst tweeter on the market is this regard. You must take this into account for automotive use. Look at how far down the off axis frequency response is at 10,000hz.Poor low frequency response - Don't let the low resonant frequency and massive magnet fool you. This tweeter has a massive impedance peak at the resonant frequency which makes passive crossover design very difficult. If you have a passive highpass crossover designed for this 4ohm tweeter at 3000hz when the impedance peaks to over 10ohm check what frequency your crossover is now working at. Do not even consider using this in a passive 2-way system as the sound quality becomes very poor at anything above moderate volume.Very fragile and easily damaged - treat these extremely carefully as a light touch can damage them. Below average build quality. Bend the plastic faceplate and you can also break them. The terminals can easily snap off.Excellent high frequency detail - Like a dedicated race car this tweeter is only good at one thing. You will not find a dome tweeter below $200 that will beat the Vifa xt25 in accuracy, detail and overall sound quality. It must be run active with very steep crossover slopes if you want to run 2-way. Running passive stick to a 3-way design with a dedicated 3 or 4inch midrange.The magic happens when you do both, run active and run a dedicated midrange. You will have a setup that can not only provide exceptional high frequency detail, but reach volumes that you would never have thought possible.I have installed this tweeter in over 20 different setups, from 2-way passive to 3-way active and have experience with more than 10 other large format tweeters.

Rated 5 out of 5 by from Extremely nice tweeter!! Vastly superior to other Vifa's I have usedI'm using this tweeter in a two way, large bookshelf paired with a Goldwood GW-10PC-8 10" woofer. The tweeter is crossed second order at around 2400hz. I used the XT to replace a Vifa BC25SG15-04 and the difference is night and day! The BC was always harsh in the 1-2k area even with LCR network. I dropped this XT in without any changes to crossover or attenuation network and WOW! It sounds so buttery and smooth. Vocals are so much cleaner now and the top end sparkles, crisp and clear with zero harshness. It is interesting to note that the BC tweeter is rated 2db higher in efficiency, yet the XT sounds a bit louder using the same attenuation network.I highly recommend this tweeter! It may be the cleanest and smoothest one I have heard. You will certainly discover new details in your music. The dispersion is amazing. Two rooms away and the highs sound almost as clear as in the same room!

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.
Asked by: Miketoo
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.

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?
Asked by: Icantusemyrealname
You don't need to build an enclosure behind this tweeter. It is sealed.

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!!
Asked by: Halcyon
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

Is this for one tweeter or a pair?

Asked by: nice186
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.

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 ?
Asked by: wsissons
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.
