Are cheap Beryllium tweeters any good?

Would love to see same tests for the 2-4 inch cheap domed midrange speakers from China.

Chinese factory workers are forced by ccp to wear caps that read their thoughts. Google it

Focal Utopia headphones were some of the first audiophile top tier headphones to used beryllium drivers and were said that's part of the reason why they cost a few grand. But a few years later Chinese headphone manufacturers started introducing models with beryllium drivers under $500....That shown me it's only a matter of time when this material will trickle down in cost for other types of drivers besides headphone types. Good video info.

Thanks for this review, I've been really curious on the Peerless and Vifa brands.

Maybe they are only Beryllium coated..

Isn’t beryllium extremely toxic?

Why the scepticism? Named brand beryllium tweeters are $400 because there are distributers and retailers who take their 100% profit margins. These Chinese manufacturers are taking may be 10%. If it measures like beryllium then it's a great deal!

Thanks for a great and detailed review. Just what I wanted to know.

The first speaker to use beryllium domes was the vernerable yamaha NS-1000 launched in the late 1970's. I still own my original pair and they still sound amazing.

I don't like the beryllium sound.

what about titanium tweeter?

I have the Blisma T25B and the no name MeloDavid and they sound almost the same hard to hear any difference, the distortion is so low. The advantage with Blisma it to cross it a bit lower, however you have to pay for that feature true your nose. The MeloDavid is a bargain whatever you compare it to! However Beryllium have long run in time, they sound good from the beginning but get better with time like a fine wine.

How about a link to the tweeter ?????

The issue with ceramic, metal, and other very hard materials is that where there breakup happens it is much more severe because the material isn't inherently damped - it's stiff. A hard breakup at 18-19k on a tweeter may not result on anything audible for most people. For something like a 6" cone the breakup of a metal driver would very possibly land in the middle of the audible range and where it's trying to integrate with a tweeter. That can be absolutely terrible. So you will be likely to see steep crossovers used on those extremely stff coned drivers and or lower crossover points. For any of them they can take steps to dampen the cone for the breakup but that will add cost, and likely hurt sensitivity. All kinds of interesting trade offs!

These look great though.

You promised to put a link in the description. Can you add a link?

I’d like to try these. Was the one you declared the winner the 25mm 8ohm on the eBay page?

Cone break-up = break-up ;)

A dangerous substance for entertainment purposes ? What's next gun powder woofers?

Useful but too long. Please consider making 5-7 minute videos. Of course, it would mean that the text has to be carefully considered and scripted. And no “thinking aloud” on camera, but on the other hand, it would bring more followers and viewers.

Beryllium is produced in China, US, and Kazakstan. China leads in production of the material so it makes sense they would make things out of the stuff.

Of course not it's made in china

i have scan speak berillium , made in china, super good and expensive. i dont have cheap

try these i like them i used 2 different but mostly same units i sure you can find them in many stores Timpano Audio TPT-ST2 4" Super Tweeter Pair

You can hear the harshness at 18-19k ?

TAD TD4003 Diaphrams around £4000 each .... Read up on vapour deposition ...

beryllium is a very dangerous element especially in dust form. Read relevant safety sheets!

U0m a big fan user of yamha spkrs.- they don't sound hard. good design. caution be is extremely toxic to humans. so if these are be domed, if they break through overload. must be isolated,safely disposed off. bagged. do not touch be or breathe in powdered fragments. danger is very real. causes cancer.

I bought the same 8 ohm versions with the 25 diafragma, controlled by a dsp, it is a very very nice tweeter, but it has that extreme S problem, with peaks from 4 to 8khz. the control, equing it out it gets very enjoyable, there is a lot of nice detail compared to the sb 29 mm ringradiator. i also think, that the frontpanel causes some honky ponky peaks , i am currently working on a waveguide for it.

I have contacted the seller (on Ebay) for these recommended tweeters, stating that I will give feedback providing they are real beryllium using a spectral analysis and can they confirm if they are genuine or not before I go ahead and purchase! Guess what, no reply from the seller! I guess they don't want a sale

I just want to point out a couple things.
He is comparing a 19mm tweeter with 25mm ones. Obviously it's going to look bad.
He is comparing a soft dome tweeter with hard metal and ceramic tweeters. Obviously it's going to look bad on THD plots. They don't even need to be berillium, because aluminium measures equally low distortion.
SB26ADC would fit that role better. Berillium is supposed to have better decay characteristics, so it would be interesting to see some waterfalls too.

Also worth noting that tweeter design is not just the diaphragm material. Suspension, quality control and everything that's behind the diaphragm are important. The best manufacturers like Kartesian or ScanSpeak even pay attention to venting behind the suspension to make sure it isn't affected too much by it's' back volume.
Thank you for the comparison RAW-CAt. You took the bait and did the work, so I'm grateful.

How people became audiophools to buy 0.0001% THD amplifiers at high powers to drive speakers that cannot reproduce better than 0.1% even at low levels.

To my knowledge They make the dubble magnets like that to reduce the effects it could have with a TV If it was close, But I don't know if modern tvs are sensitive to 🧲 like the old ones they are called bucking magnets 🤔

No offense but you can’t cross a SB19 at 1kHz or a cheap chinese tweeter ar 700Hz. Measure at 100dB at 1m.

Do not buy tweeters in Ali😂. I have bought all of them.. and all are shit

If you need exelent tweter test. T330d esotar they made also china !

People here claim that the Chinese lie, cheat, and rip-off etc. It seems that their ignorance blinds themto the fact that everything is made in China, from lower cost to higher cost products. Do some research, people.

Got a pair yesterday from AliExpress. Each is in a plastic bag separate, both in a foamed carton box. But getting one out the plastic bag, I got immediately a toxic reaction with my inhalation.... Took them out yesterday afternoon, now in the morning it is a bit better. How harmful this is?

Make a small strip out of steel and one out of berillium and the steel one vibrates after flexing it but the b one won't. It acts like lead yet it's as stiff as steel.

>repeat dialogue, paragraph/plan your content- anything in any order rolls out your mouth, 48 & 96 are sampling rates nothing to do with freq range.

big like from "ISRAEL" !!

The extra magnet on the ring radiator tweeter is a “bucking magnet”. "Bucking magnets" have NO effect on the SPEAKER operation, their only purpose is to "cancel out" the external magnetic field of the main speakers magnet so it has a minimal effect on TUBE tv screens (LCD or plasma screens aren't effected).

Cone breakup of a dome. Hell of a geometry.

B&W is diamond beryllium is focal

Comments are critical of omitting factors, but RAWCAT bro does great job showing how these tweetrs PERFORM with RAWCAT's tools and honest feelings. This is a great resource for ADDING to other data viewers / purchasers have. Fir his part, great video!!!
