I have thanked you before, but wanted to thank you again for taking your time to share your knowledge. I try and watch all shared videos and I think I am taking away valuable information with each video. I will say I purchased a couple of the dual open baffle subwoofer kits - I'm still trying to get them integrated into my 2 channel setup. I will say the subs performance is exceptional and that the open baffle experience is different than my experience with sealed and ported subs. I've been putting a lot of thought into some of the full range open baffle kits.
I've been an audiophile for the past 49 years and I consider myself uncurable. Carver Platinum's have a 60-inch ribbon and 4 12-inch woofers. The sound and detail are phenomenal. While listening to these it helps a lot if the volume is raised a bit to fully appreciate the wonderful detail they produce. I just delivered my only pair of these as a gift to an appreciative friend during Christmas and then purchased a pair of something new to replace them with that sounds phenomenal, even while playing at a low volume.
Great educational information. Thank you Danny. The ribbon tweeter wouldn’t last with my grandkids around. I’d have to stock up on replacements. Really interesting.
I have a 40" planar drivers that go down to 250 hz. One of the important points is since they are fast the driver below needs to be fast enough to match the ribbon/planar etc. Differences in speed between drivers makes it easy to hear transition between drivers.
I really enjoy planar tweeters. Rocking some Chane/Arx speakers and planar tweeters are so easy to listen to and detailed. Can't imagine going to a dome metal tweeter again after my last set of speakers.
Danny I'm glad I found that you had shared this video on ribbon tweeters. I have these very well made ribbon tweeters that are only marked with a code marked on them. They came along with east teach mid woofers or were paired with them. They are very shallow yet the film is yellow (ribbon). See I needed to ask about there application. And please talk about stiff woofers that are aluminum coned.
That was a Amazing class on Tweeters 🔊🎼. Thank you for your great video and the knowledge that you give us in every video . I got a question in what you think of the KLIPSCH RF 7 lll SPEAKERS ( QUALITY , RESPONSE🔊🎼 ) ?
Thanks for the chat. Turns out my super tweeters are planar not ribbons lol. Your certainly right about taking them apart I had a nightmare with mine when I got curious what was inside them. Fortunately I didn't break it 😁 Would have been nice to hear your thoughts on ring radiator tweeters as I'm currently thinking of replacing my normal old dome tweeters with them (probably vifa XT 25 type).
Learnt several new things so thnx m8 👍🏼 Some of those planar tweeters looks (and probably performs) similar to ps audio’s planars in their FR30 series/model 👀
I really like ring radiator tweeters. They have pretty good dispersion and, because they use a silk membrane, they provide a very sweet tone but not necessarily the most accurate reproduction. Peerless (Vifa) has some that are exceptional value.
@@jamegumb7298 ? How? Most of those tweeters have a really low resonant frequency and fairly high power handling, so something must have gone very wrong.
@@mndlessdrwer I looked at them again, they lacked the ring, so simple soft dome. The amount of power the amp puts out is 1.5× what the speakers can take so should not be overly deformed sound that did it, RIAA amp works great as always, nothing likely to have gone wrong there, wires 4mm² wires in banana plugs seperate wires for tweeters and woofers, nicely clamped and nothing sticking out or loose. I really have no clue, other than Callas voice going too high and poof tweeter, the other option being the speakers being far from what was on the box, power handling wise, but even then volume was well within limits. I am building my own now for that system too, should not happen again.
Really enjoy your tech talks. You mentioned the long plainer tweeter dispersion was limited to the length of it. Does the shorter ones have the same characteristic. IE, the one you had taken apart. I would want the tweeter to have a good horizontal and vertical dispersion. Seams to me the dome tweeter is the best solution for a two way speaker. 36" tower or book shelf.
The shorter the tweeter the wider the vertical dispersion. The longer it gets the more it is limited to the length or less than the length of the diaphragm.
Great, informative discussion on tweeters, types and characteristics. Briefly, do ceramic metal dome tweeters have the same sound/issues or are they different?
I find the soft dome silk tweeters sound the best if you dont need high volume thyre the best and are very forgiving if the crossover point is too low they dont distort too unplesantly, For high volumes titanium compression horn tweeters are the best.
Hi Danny, I have a pair of DIY MTM speakers using a pair of Vifa P13WH-00-08 5 inch woofers and a Scanspeak 2905/9000 tweeter crossed over at 3800 hz. I've thinking of replacing the tweeters with an AMT tweeter, specifically the Dayton Audio amt2-4 tweeter. Do you thinks it's worth the bother? I would of course change the crossover to suit.
Great video, easy to follow! May I please ask you to explain why many are considering the NEO 8 and 10 as mid-tone? It looks like the NEO 8 goes from 4KHz to 12.KHz or am I reading wrong?
good presentation. Can you tell me please, do aluminium tweeter diaphragms deteriorate or lose high frequency response by work hardening at the outer edge of the dome? thank you for your videos.
@Danny Richie @New Record Day Thanks so much for sharing all of your knowledge and insght with the DIY community, Danny! These Tech Talk Tuesday videos are absolute GOLD. :thumbsup: In addition, I LOVE the information that you have provided (with tests to back it up) regarding *Driver Burn-In* as well.

On a Side Note, do you have any knowledge or experience with the new *Graphene* speaker cone material? Supposedly it is both lighter and more rigid than Beryllium, and also exhibits superior damping properties. I got in early on the crowd-funding campaign for the new *ORA Sound Graphene-Q* headphones. I should have them in-hand or "on-head" in a month or so, and I will be comparing them to several of my existing high-end headphones. The inventors/designers had previously made an excellent Ribbon Microphone using their Graphene ribbon element, but that is a very small & limited market, so it did not continue into production. www.indiegogo.com/projects/ora-the-world-s-first-graphene-headphones#/ I think that Ora Sound chose the highly popular headphone market as their first major project this time in order to gain the largest amount of funding to further their R&D in refining their proprietary & patented manufacturing process. I believe that their ultimate goal is to supply OEM driver manufacturers & loudspeaker companies with custom Graphene-Q cones and/or complete drivers. I use several of your GR-Research drivers in my DIY speaker systems, including the M165X, and I wonder how this new Graphene cone technology might benefit their performance? I'm sure that use in tweeter diaphragms could produce very interesting results as well. Also, take a look into the newly announced DIY *Purifi 6.5" PTT6.5W04-01A midwoofers* which IMO have "Next Level" measured performance using a very unique surround profile and a 4-layer LMS, Ø39mm/24mm tall voice coil.

i have been looking into drivers lately, so much new stuff since i looked into it 15 years ago :) Have been doodling some concept speakers, the tweeter makes the build for sure. lowering the crossover to the woofer make a big difference. Aurum Cantus AST25120 Aero Striction Tweeter interests me, think its ribbon, but it goes down to 700hz, 1000hz recommended minimum crossover. that is really low.
Those are really too tall for a single tweeter. The height really limits the vertical dispersion. And on that model I don't think they measure as well or as smooth as they claim. I think I have tested one of those but it has been a while.
thanks for reply, Danny. its all about how you know how to use them as you say. i wont be making tweeter arrays or if i did Raal have a 9" lazy ribbon tweeter for that.
You cd consider a new ceramic dome 32mm tweeter from Peerless, model number DA32TX00-08. Shd be able to cross down to 1500 or possibly lower with a 3rd order crossover
Great information but you left one important driver out and that would be the compression driver! I kept waiting and waiting thinking you were going to pull one out but I guess you didn't have any around. Would have been interested in seeing what you think about those!🤔🤔🤗🤗🤗😁
I'm not Danny but--compression driver: super light weight diaphragm, fast, detailed, I average 1 to 10 milliwatts driving mine to normal levels, require a big horn to make them work, low end cutoff determined by horn size/length. If they play low, mine go to 300hz, they make lousy tweeters.
@@johnlebeau5471 Really appreciate your input!🤗 why do you say compression drivers are horrible for tweeters? I have a compression tweeter in my jbl's thar to me and again that's to me sound fabulous especially the Tweeter area!😨🤓🤗😎 I believe mine goes down to 1500 hertz. I've been traveling around looking at a lot of speakers and I love the compression driver?🤗😎😉 and yes I do understand the horn integration is a very important part of the sound that one receives when using such a driver!🙄🤓
@@bigjay1970 Compression/horns actually have a very wide frequency range. If the horn plays relatively low, I have a pair of Altec 203s that reach 300hz, the highs are not so pleasant. Mine are rated for 16khz, and they will play there, but I've seen a response chart of this horn and it starts to break up badly at about 10khz. They sound terrible when used as a tweeter. I cross mine over at 5500hz to a RAAL ribbon tweeter and they sound fantastic. A compression tweeter, with a tweeter sized horn is just fine.
@@dannyrichie9743 Thanks for your response, I appreciate it! Funny thing is, now when I watch TH-cam videos of various people pulling apart speakers for example a KEF R11 a couple of days ago I just shake my head in disbelief regarding some of low level type of Parts they use even in this type of mid highend speaker!🤔😁🤓
I understand for the first time why ribbons are not more widely used. They are fragile. Do you have any opinion about using multiple tweeters (in series, I assume) to reproduce midrange frequencies?
I bought a couple of dayton titanium done tweeters where the dome was very exposed with no gaurd or anything and I was installing one my finger slipped and plip the dome was crushed in I unsuccessfully tried to pop it out but it was krinkled n trashed. It was literally so fragile like foil, I still have the other (with a circle of cardboard taped over the dome opening) but now I'm Leary to buy another and install them what's the chances they won't get poked or whatever once there in floor speakers.... and there look totally irresistible to someone especially kids to poke just outa curiosity and it's not as tough as my dad's L100 cone tweeters paper dust caps I poked as a child! If wanna give a child a fun cheap present give a pile of old speakers to poke!
in the past I also thought that soft domes sounded better based on experience. But the newer metal down tweeters dont ring like they used to and the distortion is well out of the audible range. I have B&W speakers and the tweeter is tremendous. I think it goes all the way up to 38Khz to hear any artifacts. The distortion is incredibly low in the treble.
I found this tweeter that has a -3dB point off 600 Hz. Can I pair this to a set of 15" high Q woofers in a open baffle design? If so would a first order on the tweeter be enough
Hello Danny, Could you advise if Revel speakers are any good for 2.0 stereo. I am looking at their F328Be and F228Be models but concerned if these Beryllium tweeters are ear fatiguing? Thanks.
Well this might explain a lot since Behringer suddenly and without noticed pulled all the TRUTH B3031A studio monitors off store shelves. Luckily I did get two before the fall-out. The B3031A featured ribbon tweeters. They are no longer available. Only option now are the TRUTH B2021A studio monitors with less power and domed tweeters. I also have two of them. I'd love to learn about large horned tweeters like the movie theatre's use. I use my Behringer studio monitors for both my digital virtual pipe organ and my digital virtual grand piano's. I am searching for speaker options for use with digital instruments. I'm using 15" and 18" paper cone woofers for lower frequencies and need a good speaker setup for mid-high frequencies.
If you want a serious purpose built studio monitor with a planar magnetic tweeter then we have taken it to the next level. Check out the whole build thread: www.audiocircle.com/index.php?topic=160647.msg1713826#msg1713826 And www.audiocircle.com/index.php?topic=165019.msg1754231#msg1754231
Are the AMT tweeters stronger than the ribbons? I'm trying to find something "better" to try in car audio. Those planar drivers interest me also. Might need to try a few options
Glad someone with some members explains some planars :) i make planars on my channel and also handles these b&g a bit more in detail on how they are build. nice video ! love planars :)
Great info! Thanks. I like the idea of planar magnetics and their ability to go low, and their robustness. But you didn't comment too much on their transient response or capturing decay as you did with the ribbon tweeters. How do they compare? Would love to try a set in open baffle with open back lack you suggest. I'm currently running an open back ribbon on OB.
Thanks for the interesting video! I want to upgrade the 4" tweeter in my car. I'm limited to a depth of no more 3cm so I am having difficulty finding anything. I'm running a Kicker 5 channel amp. Can you recommend anything? Can I use a tweeter from a household speaker?
My Focal Nova Utopia speakers have pure Beryllium tweeters, but not screen to protect them. For $37,500 you would think they would have some kind of protection.
I just measured, tested, and designed new networks for the Infinity Mini that used those tweeters. They were the little monitors with the 4" woofer in the Aluminum box.
I prefer dualtweeters from experience. Softdome to handle the mid trebble, ribbon or horntweeter to handle the higher notes. Ever since i changed from 3way to 4way speakers, i have a much more relaxed upper sound. I would prefer to only use a horn/ribbon tweeter, but i haven't found one that handles the lower trebble well, and i don't want to push the midrange too high.
This actually blew my mind. Are you saying you split the highs up between "upper" highs, maybe more gentle, and "lower" highs? I have very powerful speakers but the tweeters are very ear piercing. I'm looking to replace them with something just as powerful but much more delicate...perhaps I can do both?
@@AlexHernandez-np7iq Don't quote me on it, i'm not a professional. I had a pair of Dali Blue 6006, very good rock'n roll speakers. But i always felt i was missing that hihat drum, the upper register felt murky. It was there, but murky imo. So i bought a pair of Dynavoice DF-6, simply because they had a softdome and ribbon and i swear my sound improved. I've had them for 4 years now and i love'em.
In the beginning Focal didn't had screen on their beryllium diaphragm ( the SM 9ׁ Monitor), but now they have it on the Focal Trio 11 Be. Danny Richie, you are not bad runner I must say:)
Hey Danny. Great vid. Quick question, can you please list 5 stand mount monitors (from companies other than gr) that you have loved over the years. And bonus points for why. Thanks.
@@dannyrichie9743 so let's do it! (also I think it goes to follow that you wouldn't mind recommending them because you portray an inherently democratic perspective.) but I think we'd like to hear.
If you offset the two tweeters but face them in the same direction then the time delay difference between the two of them will cause comb filtering (cancellation).
Yeah, that's what I was afraid to hear but even that close together? I'd like to know if there's a simulation software for comb filtering and so on. However! Let's pretend we would create a single ribbon with a t-shape and the center of the magnetic field is exactly in the T-section? Maybe even a Mercedes-Star shaped or cross-shaped or even round ribbon? (applies more to planar, I guess). I'm just a hobbyist starting out, so please be patient 😁
Hello Danny, can you confirm, with regards to aluminum (aluminium) dome tweeters, do they deteriorate over time due to work hardening at the boundry of the diaphragm edge resulting in loss of high HF?
I'm going to do several videos on that coming up. I'm going to document a design (maybe three) using non GR Research drivers from beginning to end. So from initial design to completed playing speakers.
Hey! I am choosing between the SB acoustics Satori TW29RN-B-8 and the Visaton KE 25 SC. To pair with a SB acoustics Satori 6,5" woofer. Does anyone have any experience with one of these two?
@@dannyrichie9743 Very interesting. You mention in this video that you may be offering the line source speaker as a fully assembled speaker for purchase. Are you still planning on this and if so when? Thanks.
@@dannyrichie9743 Great news. I am looking forward to this. I assume you'll be using the Bohlender Graebener Neo8 and Neo10 drivers for the line source and some conventional cone drivers for the bass?
I prefer electrostatic tweeters. Very fast and very light and no voice coil to blow out. Full range electrostatic speakers have incredibly clean deep bass. Mine do :)
How to tell if it will play details well? lot of tweeters sounds dull (to be more forgiving?), example being praised Q Acoustics 2020i, no equalizer could help that.
I can answer that for me after 3 years now :) It's the design (voicing) etc. partially, but Most of the budget speakers use cheapest parts inside (from biding post to crosover parts), and that really kills any potential even a cheap driver might have had.
How about 360 degree plasma tweeters? I’m joking, of course. But I’d like to know if you have any experience with them. I’ve read about them but never listened to any. The ozone would probably drive me out of the room quickly. 😂 thanks for the great videos.
I heard a pair in a speaker at a show. My colleagues and I didn't think too much of them. But who knows? It was at a show and there were lots of other factors involved.
@@dannyrichie9743 Although it's not a traditional R-R tweeter design, I've been really impressed with the price/performance of the SB29RDN-C000-4. It's my "go-to" budget DIY tweeter when it fits the application.
That wife with a VC looks the same to my own when she is in my room. I have to either do cleaning job by myself or to watch what does she do with all my attention ))

To find out with what frequency the tweeter will play normally - you need to multiply Fs by 3,5-4 (with 2-order filter).

Do you have any opinion about using multiple tweeters (in series, I assume) to reproduce midrange frequencies?
No. The tweeters' resonant frequencies don't change that way...
Lots of great information here.
Thanks for sharing your knowledge 👍
I bought a couple of dayton titanium done tweeters where the dome was very exposed with no gaurd or anything and I was installing one my finger slipped and plip the dome was crushed in I unsuccessfully tried to pop it out but it was krinkled n trashed. It was literally so fragile like foil, I still have the other (with a circle of cardboard taped over the dome opening) but now I'm Leary to buy another and install them what's the chances they won't get poked or whatever once there in floor speakers.... and there look totally irresistible to someone especially kids to poke just outa curiosity and it's not as tough as my dad's L100 cone tweeters paper dust caps I poked as a child! If wanna give a child a fun cheap present give a pile of old speakers to poke!
Great video, just wondering what you think of the KRK ROKIT RP7G4 Studio monitors that use Kevlar tweeters?
in the past I also thought that soft domes sounded better based on experience. But the newer metal down tweeters dont ring like they used to and the distortion is well out of the audible range. I have B&W speakers and the tweeter is tremendous. I think it goes all the way up to 38Khz to hear any artifacts. The distortion is incredibly low in the treble.
I found this tweeter that has a -3dB point off 600 Hz. Can I pair this to a set of 15" high Q woofers in a open baffle design? If so would a first order on the tweeter be enough
Hello Danny, Could you advise if Revel speakers are any good for 2.0 stereo. I am looking at their F328Be and F228Be models but concerned if these Beryllium tweeters are ear fatiguing? Thanks.
Well this might explain a lot since Behringer suddenly and without noticed pulled all the TRUTH B3031A studio monitors off store shelves. Luckily I did get two before the fall-out. The B3031A featured ribbon tweeters. They are no longer available. Only option now are the TRUTH B2021A studio monitors with less power and domed tweeters. I also have two of them. I'd love to learn about large horned tweeters like the movie theatre's use. I use my Behringer studio monitors for both my digital virtual pipe organ and my digital virtual grand piano's. I am searching for speaker options for use with digital instruments. I'm using 15" and 18" paper cone woofers for lower frequencies and need a good speaker setup for mid-high frequencies.
If you want a serious purpose built studio monitor with a planar magnetic tweeter then we have taken it to the next level. Check out the whole build thread: www.audiocircle.com/index.php?topic=160647.msg1713826#msg1713826

Are the AMT tweeters stronger than the ribbons? I'm trying to find something "better" to try in car audio. Those planar drivers interest me also. Might need to try a few options
Thanks so much for this awesome information. Cheers
Glad someone with some members explains some planars :) i make planars on my channel and also handles these b&g a bit more in detail on how they are build. nice video ! love planars :)
Great info! Thanks. I like the idea of planar magnetics and their ability to go low, and their robustness. But you didn't comment too much on their transient response or capturing decay as you did with the ribbon tweeters. How do they compare? Would love to try a set in open baffle with open back lack you suggest. I'm currently running an open back ribbon on OB.
Do you ever use compression drivers?? ✌
I’m still lost, lots to learn
Shearing knowledge 💪🏼
I wish there was a channel with the same content covering vintage Altec stuff.
You are a master...
What are your thoughts on Linaeum tweeters? I have a few that sound great but they just stopped working one day.
Do you know the Mundorf AMT tweeters? I’m planning on using a Mundorf AMT 19CM in a diy project.
Thanks for the interesting video! I want to upgrade the 4" tweeter in my car. I'm limited to a depth of no more 3cm so I am having difficulty finding anything. I'm running a Kicker 5 channel amp. Can you recommend anything? Can I use a tweeter from a household speaker?
Thanks for the video, Danny.
What about phenolic ring, compression, and plasma (lol, jk) tweeters?
About to try GRS planer from PE unless you suggest a better one @ 75 bucks each .
Viawave GRT 145 - audiophile drivers!
My Focal Nova Utopia speakers have pure Beryllium tweeters, but not screen to protect them. For $37,500 you would think they would have some kind of protection.
Especially with how toxic they are
I have the Infinity EMIT R tweeter in my Reference four speakers, have worked great for years.
I just measured, tested, and designed new networks for the Infinity Mini that used those tweeters. They were the little monitors with the 4" woofer in the Aluminum box.
@@dannyrichie9743 What were the results ?
@@RickMahoney2013 Maybe I should shoot a video of that one while I still have it here. I may need to hire a video assistant.

What’s the best tweeter design for studio monitors
what ya think of the folded motion tweeters?
Hello sir,
I just want to know what better tweeter select for karaoke setting? Compressor, ribbon, dome, or bullet?
VERY HELPFUL. Thank you.
Ferrofluid cooled tweeter is good?
Have you any views on electrostatic tweeters?
In the past I had Decca Ribbon tweeters.
I prefer dualtweeters from experience. Softdome to handle the mid trebble, ribbon or horntweeter to handle the higher notes.
Ever since i changed from 3way to 4way speakers, i have a much more relaxed upper sound.
I would prefer to only use a horn/ribbon tweeter, but i haven't found one that handles the lower trebble well,
and i don't want to push the midrange too high.
This actually blew my mind. Are you saying you split the highs up between "upper" highs, maybe more gentle, and "lower" highs? I have very powerful speakers but the tweeters are very ear piercing. I'm looking to replace them with something just as powerful but much more delicate...perhaps I can do both?
@@AlexHernandez-np7iq Don't quote me on it, i'm not a professional.
I had a pair of Dali Blue 6006, very good rock'n roll speakers. But i always felt i was missing that hihat drum, the upper register felt murky. It was there, but murky imo. So i bought a pair of Dynavoice DF-6, simply because they had a softdome and ribbon and i swear my sound improved.
I've had them for 4 years now and i love'em.
What is your option of Air Motion Tweeters?
In the beginning Focal didn't had screen on their beryllium diaphragm ( the SM 9ׁ Monitor), but now they have it on the Focal Trio 11 Be.
Danny Richie, you are not bad runner I must say:)
Hey Danny. Great vid. Quick question, can you please list 5 stand mount monitors (from companies other than gr) that you have loved over the years. And bonus points for why. Thanks.
That is a long discussion. I might have to do a whole video on that. I do have my favorites and don't mind recommending them.
@@dannyrichie9743 so let's do it! (also I think it goes to follow that you wouldn't mind recommending them because you portray an inherently democratic perspective.) but I think we'd like to hear.
What if we allign two Ribbon/Planarmagnetic tweeters in a T-Shape, so one is aligned horizontally and the other one vertically?
So using one as an up-firing super tweeter?
I meant both facing the same direction (front) , so the vertical as well as the horizontal degree offset will more or less the same.
If you offset the two tweeters but face them in the same direction then the time delay difference between the two of them will cause comb filtering (cancellation).
Yeah, that's what I was afraid to hear but even that close together? I'd like to know if there's a simulation software for comb filtering and so on.
However! Let's pretend we would create a single ribbon with a t-shape and the center of the magnetic field is exactly in the T-section?
Maybe even a Mercedes-Star shaped or cross-shaped or even round ribbon? (applies more to planar, I guess).
I'm just a hobbyist starting out, so please be patient 😁
Check out video's number 2 and 3 for more on comb filtering and two tweeters.
Hello Danny, can you confirm, with regards to aluminum (aluminium) dome tweeters, do they deteriorate over time due to work hardening at the boundry of the diaphragm edge resulting in loss of high HF?
There should be a video for the crossovers because after you have the drivers, you need a good crossover
He did one. Here’s the link. 🙂
th-cam.com/video/kvwsIecOqsU/w-d-xo.html
I'm going to do several videos on that coming up. I'm going to document a design (maybe three) using non GR Research drivers from beginning to end. So from initial design to completed playing speakers.
@@dannyrichie9743 Thanks

Hey! I am choosing between the SB acoustics Satori TW29RN-B-8 and the Visaton KE 25 SC. To pair with a SB acoustics Satori 6,5" woofer. Does anyone have any experience with one of these two?
Keep em comin these are great!
Have a read of review of new Viawave ribbon on hificompass site. Looks v good!

Great.
A Tech Talk on line source speakers would be nice.

@@dannyrichie9743 Very interesting. You mention in this video that you may be offering the line source speaker as a fully assembled speaker for purchase. Are you still planning on this and if so when?
Thanks.
@@tomhuffman6269 That is in the works and I have people working on it right now. If this next set of driver samples look good then we're rolling.
@@dannyrichie9743 Great news. I am looking forward to this. I assume you'll be using the Bohlender Graebener Neo8 and Neo10 drivers for the line source and some conventional cone drivers for the bass?
Nothing from BG, but close. All planar magnetic drivers. See them here: www.audiocircle.com/index.php?topic=165469.0
I prefer electrostatic tweeters. Very fast and very light and no voice coil to blow out. Full range electrostatic speakers have incredibly clean deep bass. Mine do :)
I agree with everything but the "neodynium" in the magnets. It is neodyMIUM...and I see many people making this mistake...
AMT or Ribbon for SQ ?
When you say, a smaller driver has higher dispersion, so you mean a smaller tweeter (diameter) is better ? You will get a greater soundstage?
I think it's just that the sound won't be as focused as with a bigger diameter tweeter.
How to tell if it will play details well? lot of tweeters sounds dull (to be more forgiving?), example being praised Q Acoustics 2020i, no equalizer could help that.
I can answer that for me after 3 years now :) It's the design (voicing) etc. partially, but Most of the budget speakers use cheapest parts inside (from biding post to crosover parts), and that really kills any potential even a cheap driver might have had.
Ah crud.. All I wanted to hear was the beryllium comment. "And here's the beryllium wisdom you seek.... Opps, Freight Co."
what makes my tweeters sound shrill sometimes?
How about Mylar? I've had good luck with them playing extremely loudly car audio stuff, Phillips made small cone shapes.
Do u sell car audio tweets
8 in carbon fiber , tpa3255 monoblocks,
How about 360 degree plasma tweeters? I’m joking, of course. But I’d like to know if you have any experience with them. I’ve read about them but never listened to any. The ozone would probably drive me out of the room quickly. 😂 thanks for the great videos.
I heard a pair in a speaker at a show. My colleagues and I didn't think too much of them. But who knows? It was at a show and there were lots of other factors involved.
I have inculcated more learning from watching your video, much appreciated.
What do you think of ring radiator tweeters?
Some of them are very nice. I hve some in stock. I almost whipped a couple out for this video.
@@dannyrichie9743
Although it's not a traditional R-R tweeter design, I've been really impressed with the price/performance of the SB29RDN-C000-4. It's my "go-to" budget DIY tweeter when it fits the application.
