I was looking at the Yanagisawa TWO20 and TWO2 and noticed they have the same body tube , but the TWO20 has metal resonators and the TWO2 does not . Why so ? Is it because the TWO20 has ribbed construction and the metal resonators help because of the dampening effect of the ribs ? Does the TWO2 have plastic resonators because the post to body construction allows for the horn to vibrate more so and metal resonators are not needed ? I just find it odd being that they share the same body tube . Any info or insight would be helpful .

Is it because of the marketing perception that the horns are attractive to varying markets?

The TWO20 price is around 1000 euros (at least here in EU) higher and you would like to see the same resonators ?

 

[datsaxman]

What they said. Much more similar than different, so they are differentiating.

 

[wanderso]

From the current Yanagisawa catalog: "Metal resonators make the tone clear and give an excellent playing response from pianissimo to fortissimo."
Of course their plastic resonators do the same.
So no hype, really, surprisingly.
Excellent pads in all the Yanys.

Because the bill of materials for one has plastic boosters (not resonators, nothing about them resonates) and for the other one has metal.

Glad I could answer that one for you.

Quick technical question.
Does not to OP's hypothesis about the "resonators" interacting with the posts qualify for an entry in

Vibrationalist Implements

Years ago, the famous and much missed Tobias came up with his P Ligging , which consisted of a leather strap tightly tied around the neck of a saxophone. His claim was that it changed (for the better, remember these things only ever change things positively) the sound of the saxophone, his main...

While you're at it, could you please share your thoughts about why some Selmers have flat resos, nylon domes, or metal domes with rivets? And, if they have the same resos as Yanagisawas, why don't they sound the same?

Curious,

You all are much too seasoned and sophisticated to fall for this, but when I was shopping for TWO-2 vs. -20 the metal resonators subtly suggested increased quality and hence added value.
In fact, depending on material, the metal may rust, and if the visible rivet in the center isn't properly sealed it could leak (other manufacturers may use a spot of hot glue on the back in the center with shellac around it).
I never had a problem with my TWO-20, but if I were getting a repad I think I'd go for plastic, like Selmer in all current production.

According to their written specifications, Selmer still uses metal resos on a least some horns, including the Serie III horns and the Serie II Jubilee horns.

It seems the WO20 and WO3X silver horns all have the metal resonators. I wondered why myself.

You are probably right. I owned a 2017 Serie II alto but I forget. But funny if they went back to metal after switching to plastic during the Mk VI production run (I'm NOT a Mk VI scholar).
Many US dealer ads copy the Conn-Selmer website which still shows metal resonators for the Reference 36 but that is in error--they are plastic.
I used to care, but from all I've read the diameter has by far the greatest influence on acoustics. The material is a marketable feature, and appeals to some.
My Flamingos are plastic, sound fantastic. A recent silver-plated Ref 36 was speced by the endorsed-artist first owner to have metal resonators, so the factory will do it if the buyer has clout.

 

[andre251]

I have a student with a Jubilee series II alto and I was surprised that it had metal resos in it. Purchased new from a big music store last year.

I didn't suggest I want the the same resonators for FREE ! The TWO20 ALSO has a different neck , double arms , a C#/Bb linkage , and more elaborate engraving that would ADD to the total price . The difference in PRICE for metal resonators might be $150 tops and would be installed at the same time . But with YOUR LOGIC , explain why the BWO20 and the BWO2 BOTH HAVE METAL RESONATORS ? The baritones are the same as the tenors , so WHY were they used in the baritones but not the tenors ?

 

[wanderso]

Perhaps Yany's prototype testing guided their choice, but equally plausibly it is all marketing-based and they believe they can sell more or charge more or both by including metal resonators in the TWO-20.

I think you may be asking for too much--an evidence-based acoustic or engineering purpose for a particular feature.

Perhaps Yany's prototype testing guided their choice, but equally plausibly it is all marketing-based and they believe they can sell more or charge more or both by including metal resonators in the TWO-20.

How about you, OP? Do you think metal resonators add value to a particular model?

For me, aside from the resonators and ignoring the price differential, the TWO-20 has many, many small upgrades in the design of key feet and soft materials and mechanics compared to the -02 which are completely aside from the marketed Pro vs. Elite features. I had been led to believe the TWO-02UL (posts vs. ribs) would be lighter--important to me--but in fact they were the same mass. With both in hand for direct comparison, the -20 seemed clearly even more exquisitely engineered and constructed than the very fine -02.

I'm not at all diminishing the TWO-02. It sounds fantastic and is an amazing bargain for the price. Many folks would not notice nor care about the small things that differentiate a -20, particularly if they sounded and played the same. But they are clearly present, and if they matter to you, you might pay the upcharge for them.

Duly noted ! I have a AWO2 U and that alto was clearly favored over both the AWO10 and AWO20 . Not sure of your critique of "exquisitely engineere and constructed" but ok . A few different items on WO20/O2 was not my OP . LOL . I merely asked about the bronze tenor Elite having metal vs. Professional having plastic resonators . Nothing more or less . I do thank you for chiming in .

In flagrant violation of the suggestion that I start a new thread because I might actually revive an old thread if I post this, I post this:

A Conversation That Resonated!

A Conversation with Ralph Morgan on Resonators Let me start by saying that these are notes from a conversation I had with Ralph Morgan back around 2003. His views were based on research and development which were conducted by him and others at the Selmer Company in the early 1960s. If you...
