- To wrap up these two test videos I measure distortion and provide commentary about each ribbon against one another. I was quite surprised myself :D Stick around for a test build with both of these ribbons to make the final determination.

What an amazing analysis, I have never seen this kind of videos on youtube, please keep uploading these videos.
mercenaris glad it is appreciated. Thanks.
Excellent! Always look forward to seeing the next video. Merry Christmas and Happy New Year!
Great video and great explanation about the fundamentals of distortion with the acoustic guitar too. Merry Christmas and Happy New Year too.
Thanks for the video, Ryan. I always enjoy them. Merry Christmas!
Man. Awesome explanation with the guitar. I loved it.
Excellent video, thank you for including distortion measurements as we discussed last time.
Excellent! You handled the part about HD very well. Kept it simple and relevant, targeting the areas of concern.
Thanks for the video! Merry Christmas !
Alex Oms Merry Christmas to you too :D
Great video! I’m learning a lot from these videos. Stay warm!
Love these. Great unique content!!
Excellent video, great analysis, keep doing this.
thank you Sr.
Merry Christmas Ryan - thanks for the review.
Thanks and Happy New - stinking cold here in Ottawa. Looks like A Really Great ribbon - if I have million dollars - I would buy more than a few of them.
Excellent just the kind of content I like to see
Wow great demo about harmonics Ryan!
Great job. Thx for the comparison
I just discovered your channel.. Very informative! Any chance you’d design and build a fairly efficient 2-way floorstander with the Viawave? Something with a benign impedance curve that can be used with high output impedance amps (tubes?) BTW, what do you think of the hornloaded Viawave models? Thanks....
Rick G thanks! I am starting a 3 way design using the viawave. Not sure about efficiency though. We'll see where it goes. Already have the test boxes built and started testing.
Impulse Audio Thanks! Yeah, high efficiency usually connotes pro or boutique drivers..
Have you ever tried Audax pro drivers? I dunno how they would sound but I liked their cloth domed tweeter I used before. At Madisound they have a 5” paper wideband and a 10” paper woofer in their pro series for a 3-way that seem quite linear for mid and midbass duties for an efficient Viawave project.
I can't wait to see a 3 way crossover video explained with all the datils. Do it broo. I love the 3-way systems.
Итак звука мы не услышали, графики, характеристики. Нет ни одного ролика на Ютубе, чтобы сравнить звук этих динамиков. Это ничего кроме рекламы. А какой звук никто не знает.
Nice! Love the ribbons
Greetings, would you care to measure the Dayton AMT mini-8? Or do you already have some info on those?
I'm very curious about them.
Thanks for your work, I enjoy your content greatly!
Tetrapodum I would be happy to do that except I don’t have a pair. All these tests are for drivers I own or that I’m using in a build anyways. A couple of people have sent me drivers for testing.
Just found your channel and like it very much. I have a question. Have you ever thought about comparing hard Dome tweeters to ribbon tweeters. What is the advantage of each besides cost or lack of cost. I know ribbons are much more expensive but are they that much better is my question
Dan B I haven’t really done a comparison. I wouldn’t automatically think the ribbon is better. It really comes down to what you’re trying to do. I think the dome can often sound better. Especially in 2 ways.
brilliant vid! i could see your breath distorting the door to your rear right lol xx
Thank you very much for the review! Did you have listening the Mundorf ribbon tweeters ever?
Leonid Sobolev I have not heard the Mumford but a lot of people are interested in it. I certainly would like to.
Thanks for all these uploads, I really look forward to each one. Is it possible to compare this Viawave with a 4 letter brand in future? Also comparing caps.. realise this is a controversial area also.
Will Mac haha I suppose you mean RAAL? I dont have a 7cm RAAL here or I would. Actually I dont have any RAAL drivers. And they are not cheap. If the opportunity comes up I absolutely would. As for a capacitor comparison,,, gee that would be hard to pull off. Im not sure I'd be able test them properly or show any difference. Ill give it some thought but not sure Im the guy for that job.
Impulse Audio yes that 4 letter word😁. Have a great christmas and NY
Great video! Are you going to use the Viawave tweeter instead of the Fountek now in your three way project? ;) :) Have you decided on woofer? ;)
Fear Wolf Brewery well Im still gonna work with both of them and listen and compare, but the viawave has really impressed me. The woofer will be the Motus UH205PW1 that I previously tested as it really impressed me as well. I have a few mids to try, but leaning towards the scanspeak 15m
Great video! Did you ever finish this 3 way and which drivers did you select ?
Cheers
Sorta. I did design two 3 ways, but when I began my renovation I sold the Viawaves in a big sell off. I never finished the other 3 way beyond a test box but it sounded great.
Great. I got the point of your review here.
Iv been looking for a pair of smooth running super tweeter as a top up to my two way JBL 4320 ()which stops at 15k Hz quite sharply and above) to form a 3 way system, and maybe test out adding my vintage Jensen P8P squawkerz in conjunction for a 4 way. I would like to run that super tweet above them from my active xover system, possibly at 800, and 15k for the JBL in a 3 way system, or 800, 3k and 8k Hz with the P8P and the super tweets.
My choice would be the Foundtek with money considered.
What do u think?
S
Terence Lau if crossing so high the fountek, definitely. The viawave is nice, but for more conventional applications that require cross overs below 5khz.
Awesome video!!
Who sells the violate, and how can you bring its response down to work with a system that's rated at 90 db or so?
ken cohagen it’s a guy named Roman who imports them from Russia. He is listed on the viawave website.
I just used an Lpad to bring the level down. Was something like 6ohm series 5ohm parallel if I remember right. The impedance of this tweeter is really flat so it’s easy to just adjust the resistor values until you get it where it sounds balanced. And if you use an active dsp XO like a mini dsp you would change adjust the level in the software.
Great job
Welp, this excludes the Fountek from my search. I need to cross at no higher than 2500hz in a 3-way design with SEAS Excel 6" mid-woofers, but these do not seem to perform well at 2500hz. What are your thoughts on Aurum Cantus G3's crossed at 2500hz mated to that woofer?
DjKinetec most ribbons aren’t happy crossing low, especially small ribbons. The Fountek in this video isn’t that big. The AC G3 is quite large and can probably handle 2500 without too much concern, But I don’t have first hand experience with it. Note that a large ribbon has other drawbacks. The Viawave is really good because it can handle a pretty low XO and remains short.
@@ImpulseAudioSpeakers Do you know how much the Viawave can be obtained for? Is shipping for it difficult? It seems like there aren't any US distributors. Thank you for the help.
DjKinetec there is a US distributer, last I check he was listed on the viawave website. Are you in the US or CAN?
@@ImpulseAudioSpeakers US
Looked up those Viawave GRT 145 ribbon drivers. They look well designed and hard to get. What was their efficiency?
I have a review of just the GRT 145 where I discuss the efficiency. But they come in around 98db. The manufacturer rates them quite conservatively. The sensitivity peaks around 102db/2.8V/m !!! That's a loud measurement in my shop haha.
Have you considered the B&C 6MD38 dedicated midrange driver? 96dB sensitivity and very low distortion. Zalph Audio rested it and the waterfall plots looked very good.
Nice video. Is it safety using 40uf continously?
indravatar it’s so the amplifier doesn’t see a short at low frequencies and that the ribbon isn’t over driven at low frequencies. It is safety but necessary.
Can I use or can I make tweeter without damaging it ,play some low mids frequency . And,Ike how low u think I can go without damaging it.
The Patriot Alien I wouldn’t go less than 2khz or use a compression driver.
Does the Fountek have a neodymium magnet? The peak at 1.3khz could well be a product of magnet hysteresis.
Hmm, I can’t remember but if I had to guess, it does. I’m not familiar with magnet hysteresis; and not sure why a neo would be different than a ferrite. I’ll look into that, thanks.
It's more like camera or ribbon resonance. But it is not a problem - it s below crossover frequency.
I used both tweeters. CD2 can be used with a lower crossover frequency and
Viawave is a bit better on higher frequencies. Both are good.
But use those at higher crossover frequencies than manufacturers recommend.
Texting from Toronto once again fannntastic video were have you been all my life really need some advice have custom made speakers made by a Canadian speaker co. here 2way 15in woofer with compression horn ported in front w/2ports open them up to replace caps and noticed all specs wiped off of drivers? I insulated the cabinets and replaced cap would like a quality cross over install
Were the measurements done in below freezing ambient? Cool temperatures can radically alter the physical dynamics of many polymers.... but you knew that😉.
Jennifer WhiteWolf not below freezing (doesn’t get that cold here very often) and I usually wait for a warmer day even if I do the talking on a different colder day. Besides, when it does get cold I store the drivers indoors and bring them out just for the test so they’re warm for the test. Speed of sound is slightly higher in the cold otherwise there is not much difference.
Seems like everyone’s comments lately are trying to pick apart my methods. I know what I’m doing even if I can’t give every detail in a 10min video. Why am I doing this again? It’s certainly not for the $10 google pays me. Sorry I’m ranting, it’s a lot of comments like this not just yours.
@@ImpulseAudioSpeakers The "suspensions" of the drivers become stiffer so there is definitely a difference. Subwoofers are even worse. Jennifer is spot on here.
carlos oliveira like I said, the drivers were at room temperature. They don’t cool off that quickly. Besides, I’ve done plenty of comparison testing and temperature rarely impacts performance to any noteworthy amount. Feel free to dismiss the data though. It was free information so not anything you’ll miss out on.
First view n liked the Founteks in home. Where can I buy Viatek speakers?
Chris Boylan there’s a one man distributer in the US you have to email. His name is Roman.
Chris Boylan email from viawave website: vze2frh5@yahoo.com
Or is it will b better to use a compression driver ?
Great video! Do you happen to know if there are commercially available speakers that are able to produce frequencies upto 80-100khz? I'm interested in the physiological effects of ultrasonic sound waves, and how it might be used in live music performance applications in-order to enhance the audiences experience on a subtle sub-conscious level.
Cheers!
Only if you’re interested in entertaining bats, rodents, whales, and dolphins.
The RAAL 140-15d is capable of pretty good flat response to near 50 KHz. To go higher you are no longer looking at high fidelity drivers.. there are special UHF transducers made for scientific research but the generally have limited energy capabilities, limited bandwidth, and dispersion issues... not for music reproduction, not even for hyper harmonics in wide band DSD recordings.
Efficiency is acoustic output pr electric input power. The Viawave sits higher in the reading because it's some 4 ohm's . Try presenting the same amount of wattage (power)to both speakers ( after measuring their actual nominal/average impedance,- a pocket calculator will help finding the right voltages for this test. Please !
William Kvist Poulsen I provide the impedance plots. Can’t remember (have to watch my own video to remember) but I believe the viawave was still more efficient. 4ohm is a 3db advantage over 8ohm (consumes double the power). In any case it’s definitely more sensitive.
Where abouts are you location I'm in Toronto you know Canadian made audio is awesome but I'm a Yankee audio fan own lots of amps including Canadian made bryston
I'm on Vancouver Island, little town called Ladysmith. If you're ever out this was for a vacation look me up!
I wonder how the 3.0 version of the fountek would fair against the viawave. Do you know where i could buy one of these viawave.ru/en/product_srt7
analogaudio rules if you want the viawave the North American distributor is a guy named Roman. I think his contact info is on that website.
The NeoX3.0 is not as good as the viawave in my opinion. It has a bigger diaphragm so technically can cross lower, but the viawave has great distortion numbers and super high sensitivity. Should be able to cross very low. Everything else about the viawave is better.
Ribbon or beryllium? Viawave or Bliesma? Which one is better?
My Sy I haven’t used the Bliesma so I can’t say. But I’d love to try it. Both look exceptional.
@@ImpulseAudioSpeakers
I'd like to build loudspeaker using PHL 1120 midrange driver so I have to choose ribbon or beryllium- hi SPL with details is the aim of this project. That's why I'm asking.
My Sy that will be a very nice speaker.
@@ImpulseAudioSpeakers
do you know any speaker that would match this set? something between 10 and 15 inches? I know that audio elegance is available in the USA, however, customs and VAT shipments mean that the speaker costs 2x more. what would your choice be? Peace and thank you for the answer.
My Sy can you get the JBL 2226?
How does the waves compared to the real tweeters?
Daniel Castiglione do you mean the RAAL tweeters? Not sure what you mean by real tweeters. I've never used a RAAL so couldnt say how they compare if that's what you meant.
Impulse Audio most likely autocorrect:)
I for one will never understand the need for off axis measuring - I do not wonder around my room when Im listening to my system - maybe there is some consideration for a Home Theater - even then some DSP correction can be made to improve - especially with units like my DIRAC Live correction
GLYNN TILLERY you should do some research around power response. Off axis response can be just as important as axial. Research is pretty solid in this area.
Think about it. Your speaker doesn't just aim sound directly to your ears. Some of it is reflected off side walls etc. If a speaker was only designed for flat direct sound, you would find it to be exceptionally bright and tipped up in overall balance in room. As was mentioned here, it is the power response that is more important which takes into account the reflected sound as well as the direct (total acoustic output) to produce a flattish response.
@@carlosoliveira-rc2xt one of the main reasons that planar speaker design is superior IS that the pressure wave that is uniform or "flat" as it were which decreases room acoustic anomalies ... people have been so used to dealing with the inherent problems of cone shaped drivers - that they just got used to the less than controlled dispersion.... interaction with room properties should be dealt with at the speaker level more than the hardware level ....
@@rts100x5 The planar speaker has less dispersion to the sides so interacts less with side walls. A wide dispersion speaker should not be considered inferior as it mimics real life.
Flat planar speakers have as many weaknesses as they have strengths.
While room correction devices can be beneficial, especially in the bass range, I have yet to hear one that is totally transparent in the midrange. Of course this would depend on the resolution of he rest of the system. The speaker is the final link in the reproduction chain and if you think about it your room correction is actually upstream of the speaker even though it is taking it's input after the speaker.
Wide dispersion with even power response is the way to go in designing a speaker. It has been shown to be the case and is not an opinion.
Where is the comparison? You gave a lot of technical specifications but you didn't give a comparative description of what they sound like.
Dream Diction the comparison was technical. I have another video of these tweeters in 3 way speakers with broad comments on listening impressions.
Why haven't you given me the name of the other video?
Dream Diction umm, cause I couldn't remember the name and didn't think it would be hard to find it if you wanted to see it.
Something like high end 3 way. It should be the video in my list after this one.
Here: th-cam.com/video/leTqwb9jJJ0/w-d-xo.html
You can always just ask. I can't read your mind even though I try really hard.
You give total emphasis to complex crossovers to force a flat freq/spl response, but measuring the output of any speaker at a given frequency tells you NOTHING about what that speaker sounds like at that frequency. Some of the best sounding speakers in the world have a ragged uneven freq/spl graph line. Dump your computer testing and start using your ears !
testing distortion on a true ribbon tweeter using just a 40uf cap.. ?
r. grambo what do you think I should have used? Something bigger?
good days a capacitor would be enough

Cold outside 🥶
Fontek neo 5.0
Packaging is VERY expensive and Apple are good at it because they are a trillion dollar company.
Three to six db sensitivity difference and not efficiency difference as stated. Efficiency would be stated as a percentage.
carlos oliveira sorry but that’s not the case. There’s no need to state it as a unit of percentage. I’m not sure why that would be the case.
@@ImpulseAudioSpeakers You are absolutely wrong here. I'm sure you can research it and eventually find this to be correct. It does kind of diminish your credibility though as this fact is pretty basic.
Cheers
carlos oliveira percent is a ratio. Efficiency is the ratio of sound power out for electrical power in. I stated that ratio in decibels instead of percent in this video (dB/watt). They mean the same thing except everyone understands it better as dB/w@1m. More than that most people refer to sensitivity the most (expressed as dB@2.83V@1m). Stating driver efficiency as a 2.138% vs 2.146% would be very cumbersome. Nobody does that. Those are made up numbers by the way.
But if you don’t find me not credible that’s ok too.
Нет реального сравнения звучания. Остальное - реклама.
the theorist, a lot of comment but nothing proves.
You get some info yet.
Anyways?
Spunk Nathan not sure what this means...
Viawave GRT 145 better
But if you want lower crossover frequency CD2 is preferable. I used both.
