Best Treble Unit?

Hi,

They are incredibly cheap at around $400 for a pair and could be priced $100-200 higher and still be a bargain.

When bought from Visaton the listed price is Euro 156.24/EA which I suppose is enclusive of VAT.

They used to be a lot cheaper but the nice thing about them is that anyone capable of waving a soldering iron can replace a smoked ribbon in a matter of minutes.

Actually I find them much better dynamically speaking than any dome speaker I've ever heard so I really don't know where these rumours come from.

Cheers,😉
 
MHT-12 absolute minimum fs

Hi,


how low can a Visaton MHT-12 be 2nd order crossovered (12db / octave) maximum? (So the minimum fs for the crossover, where the Visaton will still be capable of doing well not only in power but thermally too). I don't want it to smoke. 🙂

I'm just in the middle of a 2-way box design, either a TL box with a fullrange Fostex FE208ES (and then fs will be between about 7-10k) OR I'll just try to use a normal midbass which goes up high enough to be able to be crossovered with the MHT-12.

In this second case, I have to know the lowest fs frequency for a 2nd order crossover, at which the Visaton won't smoke up and will run just ok. That will of course make my selection for the midbass more easy, that's why I'm asking that all.

Second Issue: MHT-12 has a sensitivity around 91db. How can I match it with a much more sensible Fostex for example (97db) ?

Crossover will be 2nd order in any case, no changes.

Dave, ribbons have a limited vertical dispersion, don't you think it is a limitation?

At this address , you can see some non-linear distorsion measurements of various tweeters: the only ribbon measured, HI-VI RT2H, has worst non-linear distorsion compared to the Scanspeak D2905-9300. Of course this doesn't mean that all ribbon tweeters have high non-linear distorsion.

Just new here so I'm quoting a two hundred year old post 😉

Actually I haven't seen any decently priced ribbons that do well on non-lineair distortion compared to similar priced domes. Only the frightingly expensive ribbons perform well in this area, but hardly all of them. But in that case your better off with the scan speak ringrad which measures so well, you'd think someone was fiddling with the results. Just don't use it in a 2-way though.

The Millenium is an excellent performer, very close to reality imho. I prefer the scanspeak 9700 over the 9900. The latter has a bump in the highs that bugs the heck out of my ears. It becomes quite annoying after a while. The 9700 is one of the best tweeters built, without looking at the give away price.

I've seen some surprising results for the vifa X25 lately, very good for the price, though it sounded a bit too 3-dimensional / airy in the design I heard it in, I'm not sure yet. Pricequality ratio is very good on this one.

Cheers.
 
The millenium is over priced for the sound it puts out. I'd rate the vifa XT25 over it any day regardless of cost

Scanspeak make awesome mid range drivers but the 9700 is nothing special. Haven't heard or used the 9900 so couldn't comment.
 
Well, one thing is painfully obvious to me when reading through this thread... there is absolutly no concensus on what the best tweeters are. Or, for that matter, midranges. And especially not on the overall design approach that yields the best sound.

We have people that don't like the high distortion and low dispersion of ribbons (and rightfully so), and then there are plenty that just like they way they sound. Some like old flea-market midranges (no offense intended, I am well aware that some old drivers are quite nice), and some like the new high-tech Accuton or Excel drivers. There are fans of active biamping with active crossovers tailored to give low distortion and high accuracy in the final design, and then there are those that want no crossovers at all - willing to trade distortion for phase accuracy. We have some that think high xmax leads to increased headroom and lower distortion in the right driver, and others that actively seek out low xmax drivers to match a particular tweeter behavior.

Good thing there are a variety of speakers out there... and a good thing we can build ourselves the ones that aren't yet out there.

So what is the "best" tweeter? I like them all. Ribbons have a nice sound... in the same way that planar speakers have a nice sound. I think domes can be properly implemented to yield the best of both worlds though, just as dynamic drivers in a dipolar design can give the best attributes of planar speakers without their high distortion products and ragged frequency response. "Best?" Not sure there really is one...
 
Hi,

the high distortion and low dispersion of ribbons

High distortion in ribbons?
I don't think so....to me most dome tweeters are severely distorted even though it's not the same kind of distortion...

Quite frankly, as you said, I don't care either about what's best but I know one thing though, what's best on paper isn't necessarily the best in real life.

Cheers,😉

Couldn't agree more.

A good ribbon beats 90% of domes out there, this is my opinion of course.

Thanks. I'm pretty new to this and although you weren't addressing my specific question a few days ago.. You were the only one who's post actually gave me direction. I guess there is no clear answer. So, I'll just have fun and mess around until I find what's best for me. I do have to admit though, that I'll probably follow in the footsteps of the "Audiophile Speaker Giants" like Dynaudio, Wilson Audio, B&W and Eggleston. It seems painfully obvious from their results that it's easier to build the ultimate speaker using a dome then it is using a tweeter like the Raven. So, maybe I'll use my Ravens at some future date.

Hi,

Yeah.... I'm sure you're right about good ribbons being better than 90 percent of the domes out there. Now... that could either mean that their are too many idiots out there making poor quality domes and they haven't tried their hands at making poor quality ribbons yet..... or it could mean that ribbons, inspite of poorer dynamics, are derived from a better design. Anyway, The Esotar tweeters that I have are suppose to be better than 99% of the domes out there. As far as the Ravens that I have... Well... I want to believe that I could use them to build a speaker that's even better than the $100,000.00 Dynaudio, Wilson Audio or Eggleston speakers, but that's probably not goinf to happen... and there's probably a reason why these habitually successful companies don't use ribbons.😕

Though my speakers don't have a tweeter at all I'd like to throw in my 2pc.
Just because reviewers regard some models as the best speakers (no one dares to bite the hand that feeds him) doesn't mean that the "winners" are the best there is.

I have once heard a studio monitor using an SA compact driver (it was right at the manufacturers demo room in the Netherlands), some sort of a "ribbon tweeter".
Do I have to say that it was clean and transparent despite being played at insanely high levels ?
There was once a test of a small P.A. in a German mag (aimed at pro users) using the same tweeter. One conclusion was that the 12" midrange couldn't cope with the tweeter in terms of SPL and THD !!!

Hi,

or it could mean that ribbons, inspite of poorer dynamics, are derived from a better design.

I beg your pardon?

First of all any ribbon tweeter has intrinsically much less moving mass than a dome tweeter.

Secondly, they usually are an order of magnitude more efficient too so that should help dynamic rendition as well.

Thirdly, since these tweeters are nothing more than a resistive element, their impedance curve is usually ruler flat making them extremely amplifier friendly.

IOW, they won't change much in frequency response due to changing impedance.

Since these are flat devices, dispersion can be a problem with some funny designs...
OTOH very wide dispersion creates room interaction problems so, take your pick...

Dome tweeters are more often than not heavier so will have higher moving mass. Hence slower transient response.

They also often contain ferrofluid material in the voice coil which makes the moving mass higher still and impedes high transient response.

Their dome shape can yield better dispersion provided it's not difracted by cabinet walls etc.

In short, anyone considering building a serious speaker should at the very least consider the virtues of a ribbon.
The difference between both technologies is NOT subtle as anyone having heard the difference will agree.

If you don't know how to correctly integrate all speaker factors into a good design then don't start with expensive dome tweeters, it's a waste of time and money IMHO.

Cheers,😉
 
Well, I wouldn't want to say that poor measurements mean poor performance... this is simply not always the case with our current performance indicators like freq response, waterfall plots and distortion graphs. But in the case of ribbon's there eems to be a very lare gap between what the mic tells and what the ear and brain makes of it.

I beg to differ that most ribbons are better. I question if the kind of sound they produce does come closer to reality than similar priced domes. In a way I'd like to compare their virtues with electrostats, which also aren't inherently better than conventional speakers jus because they are so light. It just isn't that simple.

that's just mho.
 
I think, audiophile companies are somewhat interesting.

As the price rises, you can think about, how many dollars did you pay at that company for the speaker drivers, crossover, baffle, construction, working hours etc. and how many dollars are the rest, which is nothing else, than paying the brand.

You can look after, which drivers they use, from which supplier.

Amazing.

So don't let yourself be fooled too much with those $100,000 numbers, it doesn't mean anything except the respect of all high-end folks that "wooow what a system do you have maaan..!" - and of course the superb building quality, since at this prive niveau you can expect extremely well-built designs.

I've heard some high-ends but I actually don't believe, that their overall cost was so much, what this $100,000 tells us. 🙂 Perhaps one-tenth of the price it is worth definitely, but no more. That's marketing. (Don't misunderstand me, I didn't say that they sound bad or whatever...)

But actually, if a $10,000 / pair speaker system will be sold at twice it's price, say $20,000, well, it's still too much. But $100,000 ???

No way.

Even if they're introducing really exceptional designs, quality and materials, you never know, what will you miss from the sound. They also cannot avoid physics, impedance, resistance, wavelength, physical and electrical laws are also applying to them, as to your $200-a-pair speaker set at home. And as long as actually no speaker is capable of reproducing the sound AS IT WAS ORIGINALLY, it's a bit nonsence for me to talk about a certain system that's beyond a limit (for me about $5000 for one pair - no more even if I were multimillionaire).

The worst problem (don't see it really a "problem") with ultra high-end systems is - except of the above - that every human's ear is different. Some of us are more sensitive to highs and as such are more likely to favor speaker systems with less highs, or a "warmer" tweeter, and it's opposite and that all together applies of course to the whole frequency spectrum. But not only the amplitude is one thing... phase accuracy - same thing. Crossover slope and order - same thing (some of us thinks one perfect, the other one prefers the other design).

So tu sum it all up, the last joke and biggest joke of the whole audio world is, I think: the more we go towards more expensive systems, the less actual ones we can select from.

So, at the $400->$2000 level there's numerous manufacturers who sell loudspeakers, each of them something different than the others. You have a greater chance to come very close or even find the ideal one, which your ears will like mostly and you'll say "mmm" to it's sound. At the ultra high-end segment on the other hand, I can count all of the manufacturers on my hands, who sell their system for more than $100,000 - and that's not much in constrast with the previous - perhaps - more than thousand different pieces of boxes!

Even the term "high-end" is still completely unacceptable for me. What's high-end? For what does high-end stand for ? Who tells me, that I'm not a high-end listener, or my box isn't high-end if I play drum and bass or downtempo on it which will definitely sound on the "high-end" system as a piece of ****.
That's the problem with the whole audio and listening thing. If I begin to buy John Coltrane LP-s, ultra-expensive LP-s, pickups, all-silver cables etc etc am I an audiophile, will my friends and people and everybody look with highest respect to my system? 😕

THAT IS HIGH-END ? 🙂 I think so.

So - as many before me said - there's NO ultimate sound system for everybody, just for one and only person - YOU, NOBODY ELSE. The rest is marketing, price, subjective feelings which don't have aníthing to do with the reproduced sound, .. nothing.

---


What I can definitely say is, that I REALLY DON'T like the sound of horns (therefore my friends are always laughing at me, when I have a look at the Avantgarde Duo or Trio and think "piece of ****" about them), I've heard some ribbons (even in car-audio) and THEY ARE THE SWEETEST sound I can imagine (dome tweeters no way!), and I really miss the crisp clear fast responding deep-enough going (not 40, 20 Hz!!!) bass, the base of the sound, at most of the audiophile-grade speakers.

But never forget: this is MY opinion. And MY ears.

Yours will like probably something much more different, than mine.

And that's the beauty of music and "high-end" audio, not the brands, not the ultra-cool ultra-expensive mahagoni cherry banana etc.. finish, not the crossover, the amp, or whatever, ... and definitely not your musical taste!

By the way, I'm really sad about, how people look at "boom boxes" and speakers designed for electronic music... if one would listen to a DJ Tiesto Live set (mixed from 2 LP-s to a master tape) on a really high-quality 2 or 3-way system, ribbons, etc.. his opinion would perhaps change on the whole electronic music thing, and this was actually the worst example, since there're lots of people there, who made and still make electronic music to LPs, with analog tube devices, extremely "stupidly" generated sounds which cannot be produced by nature..

Well, audio is a taste of your ears and actual mood. 🙂 Everything else is just a tale and of course $$$$$$$.

there's probably a reason why these habitually successful companies don't use ribbons.

Succesful. Financial. Yes. Soundwise? Dunno 🙂 -> Don't use ribbons? Not my problem! 🙂 I couldn't find anything "beauty" from your list although I haven't heard all of them of course. But I'm sure, Audio Note is one of the speaker makers, which really feels my taste. (Or better said, I found the best, which my ears like mostly at the moment). On the other hand, I'm still sure, that

1) If I would buy my selected speakers, the dome would be changed to ribbons on the fly

2) I'm really stupid, since I really don't care, how much a system costs and what it uses. If I find a dome tweeter what's capable of "cheating out" my ears as they were ribbon ones, okay, I would use them. But no dome tweeter can do that. 🙂

Take it easy.

Sorry for the long posting 🙂

Then what kind of distortion? I've never seen a ribbon tweeter perform "exceptionally" well in either linear or non-linear distortion tests. Acceptable, yes. World class, no. There is more to what we hear than simple frequency response graphs, but you must remember that if we can hear it we can measure it (though we may not be able to adequately correlate what we measure with how we perceive it). If you can hear a distortion, we should be able to measure it, and frankly frank ribbon tweeters just don't have the numbers to back them up.

However, I also like the way they sound... the maggie ribbon is one of my all-time favorites. I also like the way domes sound, and in the right design they are superior to ribbons IMO. Remember, that's just IMO though, and is exactly what my previous post was above... we all have our preferences. A dozen people in this thread proclaiming that ribbons are hands down the best tweeters on the planet just doesn't make it so. Sorry.

Quite frankly, as you said, I don't care either about what's best but I know one thing though, what's best on paper isn't necessarily the best in real life.
Of course not. But that goes both ways... all the "low mass high transient response" and "flat impedance curve" paper specs don't necessarily translate into perceived superiority.

I beg your pardon?

First of all any ribbon tweeter has intrinsically much less moving mass than a dome tweeter.
So?
Secondly, they usually are an order of magnitude more efficient too so that should help dynamic rendition as well.
And what do you do with they are also an order of magnitude more efficient than the midrange drivers?
Thirdly, since these tweeters are nothing more than a resistive element, their impedance curve is usually ruler flat making them extremely amplifier friendly.
A definite plus, but not something that can't be adequately addressed with dome designs (e.g., active crossover designs).
Dome tweeters are more often than not heavier so will have higher moving mass. Hence slower transient response.
Sorry, but higher moving mass does not so directly translate into slower transient response. That's a myth of audio that I'm surprised you continue to perpetuate. Of course, you do tend to perpetuate a whole suite of myths, so perhaps I should not be so surprised after all.

Transient response is governed by f/m and inductance. Ribbons do have low m, but they also tend to have low f as well. If anything, it is the low inductance of ribbons that tends to give them extended frequency response (and remember, transient response can be clearly represented by a simple frequency response measurement... it isn't something mysterious and spooky that can't be measured).

In short, anyone considering building a serious speaker should at the very least consider the virtues of a ribbon.
Agreed. Anyone considering building a serious speaker should consider all the possible options available. But coming to the conclusion that ribbons are superior isn't a given. There are plenty of capable and knowledgable people and companies that have decided to use both ribbon and dome designs. Like most other things in audio, there are compromises and in general you can't optimize every performance metric simultaneously.

As always... choose your poison. 😉
