Raal tweeter vs domeOn 29.10.2020 by Fesho
Unlike Bluetooth speakershome speakers are built more for sound quality.
Generally speaking, its the effect of sound coming in at different times through your sound system. What results is a tweeter moving side-to-side, and sound waves releasing into the air hitting your eardrums in nanoseconds. Loose parts in the speaker cause buzzing and popping. Two components which help against heat is the axiom titanium dome and the magnetic ferrofluid. Its similar to how products have warning labels.
In the beginning stages of a relationship, the more time you spend, the more chemistry you build. A speaker needs the right amount of energy put into it to optimize its abilities, but not too much, or else everything will start crumbling around it. To summarize, high stiffness creates much more resonance frequency which in turn creates ringing.
For example, different alloys like aluminum and magnesium have low damping, but are light and stiff. Off-axis response causes sound dispersion to fluster. When the opposite holds true, sound pressure levels can either be really good, or really bad. When this happens, the speaker increases its decibel strength and it has more of an effective cone area at low frequencies.
These lower frequencies are an advantage because they require less energy to travel to their destination. But some would argue since the horn tweeter is an outdated model, it comes with more disadvantages.
In a surround system dome tweeters are better because you want that dispersion so you cannot hear the sound coming from a particular speaker it just sounds like it surrounds you instead. Noisylabs Blog. Comparison: Dome Tweeters Vs. The purpose of tweeters is to produce high audio frequencies.
We agree with the latter. But how much does dome tweeters vs.Remember Me? Beryllium Dome.

Join Date Aug Posts RAAL vs. Just curious if it was solely to compete with the Salk Songtowers or if there were some sound acoustic benefits to the RAAL.
Anyway, I will sit back and hear what everyone has to say. Join Date Nov Posts Re: RAAL vs. Beryllium Dome My guess would be that the term 'ribbon' has become quite popular in the last few years and imho 'Beryllium' doesn't have the same aura. So speaking strictly marketing-wise, ribbon is a better choice. And I think what spawned the RAAL tower was actually a customer asking if it was possible to have a ribbon tower Never a metal tweeter!
So Beryllium would go against the tendency, even the NrT was a soft Dome Beryllium Dome I remember Dave said he did a few test with some tweeter that he was considering, and found that the raal to exceptional and measurement extremely well.
There may be tweeter that are even better then raal, but i dont think will get you anything comparable. Specifically, the Focal Beryllium inverted dome unit. I've always had domes and am not accustomed to ribbons though I have heard a few in showrooms.
Difficult to convey in words. Super thin ribbon material and lightning fast response. Beryllium Dome I hope dave will read this and chime in to give us a definitive answer. Beryllium Dome From what I know about Dave, he doesn't design loudspeakers and select components based on market trends or to compete directly with other models. There are plenty of other companies that do that. Rather, it seems he forges his own path and builds a loudspeaker around his experience, philosophy, and desired performance parameters.
He's mentioned that several designs have been canned due to unexpectedly subpar performance. He poured an enormous amount of his energy into designing one that met his exacting standards. Ribbons do have known advantages over other type of designs. Likewise, the RAAL ribbon he selected has extraordinary accuracy, polar response, energy dissipation, and off-axis response.
It's not about marketing, it's about performance. One of the reasons that beryllium is not found in most loudspeakers is because it is very expensive.
Comparison: Dome Tweeters Vs. Horn Tweeters – Noisylabs
From what I've read, it does offer performance advantages due to low weight and high strength. However, just because it's expensive doesn't necessarily make it the best. Beryllium Dome Also, remember that the tweeter in the Paradigm is proprietary. It is not something that can be purchased and used cost effectively by another company. What tweeters using exotic materials are available "off the shelf", and how do they measure? Originally Posted by curtis.Forums New posts Search forums.

It cant find the domain for me People who only like Ribbons are going to ignore it anyway and people who have heard a number of ribbons over the years and elected to not have anything to do with them -- probably hear something off putting in the listening session -- which may be exactly what this fellow is noting. What has been a long slow process for my understanding is that this hobby is multi-faceted and is largely based on one's own perception. What the guy in the site is providing is distortion figures but if people hear that as accuracy then that is the way they hear it.
If you and I hear it and think there is something amiss then we can choose to buy something else and may very well do so. The fact that a few people will shout you down for preferring something else really is irrelevant.
I think the best thing is to not get caught up in the technology - I much prefer listening to speakers without any forknowledge of what the drivers are.
This way you can listen evaluate and then backtrace what it is the speaker was using to create a correlation of what you like.Loudspeakers divide their output into frequency bands. Typically they will have one or more large drive units to cover the low bass frequencies, and a single smaller unit to reproduce the treble. There are variations of course, for example there may be an additional dedicated drive unit to reproduce middle frequencies, but it is important to understand that more may not necessarily mean better as any theoretical advantages are likely to be outweighed by the additional complication.
But the idea of specialisation, using a combination of drive units, each dedicated to a particular band of frequencies, is common to virtually all loudspeakers at all price levels. The reasons why speakers are designed this way are straightforward enough. Low frequencies need drive units capable of moving plenty of air, which means drivers with large area diaphragms with lots of fore-aft travel in their suspensions to pump the air, and hefty magnets to provide the motive force.
Tweeters have different physical characteristics, though the fundamentals are similar. A very small number of high frequency Watts goes much further than a similar number of Watts at low frequencies, partly due to the way the ears and brain perceive sound.
But tweeters do need to be very agile. They must be able to start and stop quickly so they can mirror the subtle micro-architecture of the changing musical waveform, and it is this speed that helps define their ability to cover the high frequency region effectively. The reason for domes is that the shape is inherently stiff without the need to add heavy reinforcement. Any unnecessary mass really is the enemy here, as it will damp down acceleration and deceleration as the diaphragm attempts to follow the rapidly changing signal waveform.
Another factor here is that most domes can be simply stamped out using a suitable machine tool, which is the key to making them easy and cheap to manufacture. The diaphragms may be made of woven fabric or silk or even fabric incorrectly described as silk — it happens. Sometimes the diaphragms have a surface coating to add stiffness or damping, and sometimes they also come with ferrofluid Iron filings suspended in fluid injected into the magnetic gap to help damp the assembly or help with heat dissipation.
Other designs use much harder, stiffer diaphragms, often stamped from aluminium — and sometimes more exotic materials, even in a few celebrated cases, synthetic vapour deposited diamond or beryllium. But although these are some of the hardest materials available, even they have disadvantages. Vapour deposition of diamond is a tricky procedure even for the best equipped producer.
Ribbon tweeters are quite different. Rather than using a dome radiating element, and a traditional magnet system and associated voice coil attached to the edge of the dome, which is the other half of the motor systemribbon drivers use an ultra-thin flat diaphragm, typically made from a thin aluminium foil, or constructed as a metalized polymer film, though this type of tweeter is perhaps better described as a quasi-ribbon.
The Pros and Cons of Ribbon Tweeters
Magnepan make very effective use of just such a design in their panel designs. Domes, even costly ones, can suffer from structural breakup resonances or rocking motions on their suspensions under dynamic conditions.
Ribbon Tweeter Pros. Ribbons have a thoroughly deserved reputation for being special. Ribbons respond to the most subtle waveforms, and to the highest frequencies, including those above 50 kHz that are the special preserve of high resolution formats like DVD-Audio and SACD. They can easily cope with the subtle ultra-high harmonics that lie above the main part of the audio band, and which add some of the air and sense of space you will hear from a really fine recording. Domes on the other hand need a suspension to work, which introduces a hard to control compliant mass to the system, and this inevitably introduces high frequency resonances which under the right circumstances may be audible.Remember Me?

Re: RAAL vs. Beryllium Dome My experience with the beryllium and also the inverted Focals I owned in the past always presented a too bright of sound as if my listening distance wasn't within their target range. That's the way i can put it to words, they were just too "hot" and almost couldn't stretch their legs.
I also experimented a bunch with the inverted Focal woven products and those tweets were too mellow for my taste but off axis was good from what I can remember.
Those mid 90's are hard to remember Those Infinity Emits were always nice, pleasant, and composed sounding. Almost a refined soft sound. The RAAL's by far have presented the finest clarity and resolution, imo.
Almost as if the RAAL products are in a different level. Love them! Beryllium Dome I think that Tweeters can come down to personal preference. I have the Stock Nrt tweeters in my Towers.
The Genesis ribbons, and the Usher Be dome really nailed the shimmering bells. However for long listening periods, each tweeter would eventually give me "Ear Burn", something my Nrts don't do.

Is be that much better than NrT to warrant few hundreds for be? What are the best advantages of be tweet over soft dome for instance? Join Date Nov Posts Beryllium Dome Thank you Jacob for the very informative post, I really appreciate honesty over hype, I to trust Dave and as you said "since my tastes in loudspeakers brought me to Ascend in the first place".
That's why I'm here and have an all Ascend loudspeaker setup. That's for another thread though, my intentions are to thank you my friend. Best regards, Jeff. Beryllium Dome well i dont think any of us would be to fully enjoy raal extreme extension, but i think there is is more to it then just FR. The raal version is flatter, and also with imevements in decay time. If i get the tower i would go straight raal, simply there isnt anything close in the market at this price.
The only thing that is holding me is because im from abroad and it will cost too much to take advantage of the 30 money back, if i happen not to fit my liking. I have even evaluated the different forming mechanisms from vapor deposited to film.Provided by the courtesy of the signers.
Alex, finally I could meet you at the CES 09 in Las Vegas, where I heard your own speaker project on classical music - it was utterly natural sounding. You seem to have a very clear idea in mind how natural music sounds. That is rarely experienced in the pro-market Having used your tweeters in my own designs for about a year now I can totally confirm that your tweeters were able to take the overall performance to a new level. So far, I have been skeptical about ribbon tweeters, since all I heard sounded somewhat thin, colorless and with an aluminum-rustling noise to them.
Now, I am sure, your tweeters are the most disappearing ones on the market - that means that they seemingly neither add, nor substract much from the incoming signal. Plus, their extended hi-freq. The fast growing demand of your products worldwide is for once a true indicator of how good they are.
My most upright congratulations. Aleksandar, thanks for giving us such fine products to work with. Audiophile speakers are like a great meal - you have to start with excellent ingredients in order to make a fine presentation. The RAAL ribbons have allowed us to kick it up a notch!
Dear Alex, after analyzing many higher frequency drivers for our loudspeaker production, we came to the conclusion that the RAAL ribbons are of the highest quality one can find. Our advanced Comsol multiphysics software is used for modelling the loudspeakers. The test of your various models reveals that —if filtered correctly- the results in sound quality are astonishingly good. Very high sound levels can be reached with moderate distortion. The speed and dampening are exemplary.
Tolerances are good and stability in practical use is excellent. So we decided to use your products for our new production series of two of our brand-names, the Crystal loudspeaker and the Pantheon XX by Siltech. Dear Alexandar, I have worked with Ribbons of all types over the last 30 years. I tried Technics, Visaton, Decca, Fountek and many others. Having tried your Ribbons i have for the first time experienced something like perfection. The sound is ultra pure and neutral.
I hear details in the recording such as low level sounds from the recording studio and ambient clues like newer before.
Strangely enough, this ability of your tweeters never interferes with the enjoyment of the recording. They never sound sterile or analytical. You also solved the age old problem of comb filter effects and vertical beaming with your foam pads. Manufacturing quality, looks and measurements are all to a very high standard. I can not wait to hear the version with amorphous core transformer.
You lifted my life as a music lover to the new heights. I was floored the first time I hooked up the Ribbon driver! The sound is so alive and open but without sounding harsh or distorted. The stereo image of my custom speaker systems is so very accurate and precise. It is very important to have a pinpoint sharp stereo image when recording and mixing music.
