Manuel Rincón for the testing I can’t exactly recall. 40uF maybe. For speaker design I would use second order or higher. I have only used it with 3rd order because the low end needed an aggressive slope. I can’t recall the values. 10uF, 0.6mH, 8uF maybe. Plus an Lpad. Every speaker will be different though.
Fear Wolf Brewery actually thats a really good question. The protective cap does change the response slightly. Problem is, theres no choice. I cant test without the cap, so its something we have to live with. Thankfully the effects are below where the tweeter should be crossed so it doesnt make too big of a difference, but its worth considering for sure.
I have also been pondering similar. Do others use this protective cap method,his this standard practice when measuring tweeters? Do others limit the frequency sweep instead, or perhaps Soundeasy can't sweep?
Hi. What is the best crosspoint frequency for the fountek neox 2.0 ? My midbass have 30 -6000 Hz. Now i have crossover with 2300hz crosspoint .Do you think that it is safe ? or is it better to go higher

Great video again! What are you thoughts about this tweeter? Would it be suitable for a floorstanding three way or is it only suitable for bookshelf speakers? Are you going to test the fountek neoX 3.0 too?
Fear Wolf Brewery It can be used in a floor stand speaker, but it's a bit of an animal to tame. And needs a mid that can play really high. I'd probably cross this at 3.5khz or something. Funny you ask about the NeoX 3.0 because I helped a friend design some bookshelf speakers with the 3.0 right before I started the channel. I could test them but he'd have to take the driver out of his favorite speakers for me to do it. I believe he plans on refinishing them one of these days so there may be an opportunity eventually.
Hi shir! First, sorry for my English, I, m Basque! My behringer 3031a monitor tweeter is broken. I have to replace one of them. I don't, t know if it is worth to change it, or both tweeters or will be cheaper to buy new monitors. I use them to mix music in my home studio. Best regards from Elantxobe, Basque Country!
Oooooooh exciting, I spotted a #scanspeak 👍...what would Dayton say 🤣😄. Quick question, why the cap? Wouldn't it be easier to limit the frequency sweep? Ive been pondering this for a while, how to protect the tweeter without XO for sound and impedance measurements but can't seem to find much info, perhaps it's just not necessary for a limited one or two?
MrFrobbo ya I suppose you could just limit the sweep in the software. It would basically have the same effect. I can’t think of any reason why not. I’m just use to doing it this way I guess. Well now that I think of it, if you accidentally ran a full sweep or had amp turn on thump you’d be sorry you didn’t use the cap. Seems the most secure to me. You don’t need the cap for impedance if using one of these low voltage devices like DATS. Better to run it wide open and get as much data as possible.
If you look at the impedance of the Fountek ribbon, it drops down to almost 0 in the stop band. Not only ribbon tweeters are more fragile at the lower F (stretched or ripped foils may occur) but you can also damage the amp. This sort of the impedance is actually fairly typical of many ribbon tweeters, not just Fountek.
I messed around with the NeoX 2.0 using a digital crossover and managed to flatten it out. The one thing I would say is that it seems low distortion which is an advantage over the dome tweeters in a similar price bracket but I couldn't live with the vertical dispersion.
snibeti snab-xD a capacitor placed like that acts as a high pass filter and DC block. Because ribbons are fragile it’s a good idea to keep low frequencies off them. Also, in case of an amp turn on thump or an accidental unplug/plug of a wire that cause crackle or thump, the cap will block those damaging inputs. That’s how the cap protects the tweeter but probably more importantly it protects the amp, because ribbons go to 0 ohms as frequencies go down towards DC.
Tarek Z mostly because the frame is too big on that mid. Center to center spacing between the mid and tweeter will be important. The Morel has a great frame for a dome mid.
Exactly what does that mean? Sorry for a dumb question but very new in this hobbie. Do you mean that the center of each driver needs be be a certain distance? Is there a way to calculate that?
Fear Wolf Brewery no problem Wolf. I should have known that would confuse someone. Basically it's important to keep the drivers as close together as possible, at least when crossing the drivers above say 600hz. At low frequencies this isn't as big of a deal. The Morel has a frame that allows the center of the dome to be spaced close to the center of the tweeter. Now you're wondering why they should be close. That's difficult to explain by a single post. I do plan on doing a video about this. If you check out Part 3 of my Life S5 video series I touch on this briefly. I'll get something out with more details eventually.
@@ImpulseAudioSpeakers | Sounds interesting, I am curious too. I thought about a 3-way MTM construction where the high and mid chassis are tight in the middle [NeoX2.0 + Dayton RS52AN], and two Dayton RS225's (800Hz max ) arranged tightly around them ... schouldnt take too much space considering a really big Ribbon like NEOCD2.0 demanding almost the same space in length :-)
Thanks Ryan. Just for info the designer of Vituix mentioned domes should be fine on sweep as long as the drive voltage is kept at a max of 2V, ribbons are another story due to their impedance crash, full sweeps are fine too. Ribbons need protection.
Oeh, you got some more SB Acoustics midwoofers to play around with. 5inch MFC's from what I can see. I myself have 6inch NRX's. They're well build drivers. The poly cones should give very controllable break-up something that makes the NRX's a bit more difficult to work with.
Hi, I’m buddylee123 over on AVS forum. Have you thought about testing the ScanSpeak Illuminator D3004/6040-10 Beryllium Dome Tweeter before? Another great video by the way.
Shane I'd love too test that tweeter! But it costs a lot and can't spring for that. I buy most of these drivers for projects. The Viawave is a loaner and a few other exceptions.
What tweeter frequency divider have you used? 20uF? 30uF? What is exactly the capacitor you recommend? Foundek recommends 2300Hz 2nd order.

I have only used it with 3rd order because the low end needed an aggressive slope. I can’t recall the values. 10uF, 0.6mH, 8uF maybe. Plus an Lpad. Every speaker will be different though.
Good video, Ryan. I always enjoy the driver tests.
Love your detailed review, subscribed right away 👍
Thanks for your reviews and tests on youtube!
How do you get an appropriate frequency respone when you are protecting the driver with a cap? Sorry for dump question, trying to learn.:)

Stoklasa Jiri that’s pretty good I think if you take it easy on it. But generally I’d go a little higher. Can you hear any distortion?

Uskisman changing the tweeter would be a lot of work. Can you find an exact replacement? That would be easier.

may i know what app you use for test the crossover and can be use for passive crossover??thats so interesting...
xsim
What is the cap for? Is that acting as a highpass filter to protect the driver?

good afternoon. Tell me in which program you are setting up the tweeter.
One Gogh I think you’re referring to Xsim. The program near the end of the video where I show the XO work?
@@ImpulseAudioSpeakers Yes, Xsim!. Is this the demo version you have on the link?
One Gogh hmm it might be as I did beta testing for the developer. But I thought it was the same version as what’s available out there.
not trolling or anything but please ESPLAIN why the cap in line with the tweeter protects the driver...
snibeti snab-xD a capacitor placed like that acts as a high pass filter and DC block. Because ribbons are fragile it’s a good idea to keep low frequencies off them. Also, in case of an amp turn on thump or an accidental unplug/plug of a wire that cause crackle or thump, the cap will block those damaging inputs. That’s how the cap protects the tweeter but probably more importantly it protects the amp, because ribbons go to 0 ohms as frequencies go down towards DC.
Awesome content as usual.
Wouldn't you normally use a notch filter to tame the 1500Hz peak?
Programentalist you certainly can. But they require 3 parts if using a passive XO. Trying to hammer it out with the XO slope is usually my first try.
Why not the Dayton RS52AN dome mid instead?
Tarek Z mostly because the frame is too big on that mid. Center to center spacing between the mid and tweeter will be important. The Morel has a great frame for a dome mid.

MrFrobbo totally agree. I’ve driven domes full range over 2.8V and never had a problem.
So, the moment is at hand, i'll build a 3 way system with these NeoX 2.0 ... thank you for your efforts to bring us the news ;-)
What do you figure for the woofer and mid-range speakers?
Oeh, you got some more SB Acoustics midwoofers to play around with. 5inch MFC's from what I can see. I myself have 6inch NRX's. They're well build drivers. The poly cones should give very controllable break-up something that makes the NRX's a bit more difficult to work with.

Impulse Audio completely understandable, I have an idea that I want to run by you. I will shoot you a message over on AVS forum in a few weeks.
Shane sure sounds good.
Hey, it would be super useful if you would also measure the distortion. Maybe use Arta and sweep. Thx
NackDSP check out the comparison video with the viawave grt145 where I show distortion results.
U mount it On Axis at 45 and u have perfect flat response :-)
Nikola Vrckovic haha that’s one way of looking at it ;)
The Fountek Neo X 1.0 has a much better response at around 89 db efficiency.
