Hello to everybody,
someone has tried to replace the standard plastic resonators on 901 or 991 with metal (noyek, domed, flat,...) resonators?? :twisted:

If yes, which the differences?

:cheers:

Kenny,

Since the issue is not exclusive to the 901/991, I suggest that you search on the topics of resonators for a broader response.

Thank you, I will search :)

I have set here my question because it is really on the Yani that I would like to know...;)

I think I'm right in saying that the 901/902 have plastic resonators as standard and the 991/992 have metal as standard. It's a few weeks ago now since I checked and I have a memory like a whadayacallit so I can't be certain.

I got a new 991 today - plastic (until I replace them) :D

AFAIK, you're right. The 901 and 902 I've played had plastic, I think the 991 had metal (don't quote me), and my 992 has metal. Only difference to my ear is more volume. Maybe.

I play tested all 4 - 901/902/991/992 and they all sounded very similar to me, although admittedly I'm only a rank amateur. They were all very nice but at the end of the say I missed my KW :)

The Yani web site or sax.co.uk would settle the spec on standard resonators.

Do you really think the material of "resonators" makes a difference? I find it so funny that the term "resonator" is even used to describe these things. Do they actually "resonate"? Do they vibrate in any way? No. So what are they doing, really? Nothing.

Lesson? Resonators is the last thing you should worry about.

"Reflectors" is what they should be called. "Tone Booster" is a term sometimes used and more appropriate than resonator, though I suppose the reflectivity of the resonator may in fact help support some resonance in the sound column of the horn.

I had two identical Yani sopranos and outfitted both with black roo pads - one with domed plastic and the other with domed seamless metals - all resonators were the same size (key for key on both horns).

Once I had both horns set up with a solid pad and neck cork seal, I couldn't tell the difference as a player nor to the listener.

Just for the record:
S990, A880, A990, B991 - all plastic resos from factory
T992 - metal from the factory

seems like Yanagisawa might think that it makes a difference...

Thanks for your lesson... do you know if "resonator" it's my first worry? :badgrin:
I'm so sorry...I have used the term "resonator" (I have not invented it) because this is the common term to describe these things...
So they doesn't do anything? :doubt:
If it is sound what it passes inside the instrument and not simple air, they reflects the sound as mirrors and they must to do some difference.
This can be subtle and not easily noticeable if you use a dark sound setup...

Ed, have you tried to use a little more bright setup (but the same for both)?

I think I used a Ponzol M1, a Riffault, and a Super Session when making that assessment.

Now (seriously) size does matter. Reso/no reso does matter. But basically, I think that the sound is just reflecting based on the reso's size and (maybe) its shape.

So you're trying to give a lesson on acoustics to an acoustician?

Absolutely...;)

SaxyAcoustician: any lesson, clearly

Indeed, there are so many, (too many, only a business fact?) types of "resonators" in commerce, it's arduous to think that each makes a different shade of tone...

I'm not a technician but it sems that modern (of good quality) plastic "resonators" are enough hard, thick, large and with a very smooth surface, almost mirror-finished, then, if their function is to "reflect" the sound,they perfectly do this work and perhaps the difference it is only theoretical

But you mean that there is not any difference in this sense (among plastics / metal) or in absolute sense (without any type of "resonator" / with)? :?

Anyway, my question looked for a small shade, one variable, my Yani plays very well (with plastics) and yes, this matter is really the last thing that worries me :D
