Hello Guys,
We have currently on a french forum an open point concerning alu and ti dias. Persons with 4343 and others JBL from 43xx, consider that Ti is smother (less ttssss... tttssss...) and more natural than Alu. Here, it's the opposite.
Do you have an idea why?
I can understand than people from different culture could prefer different sound, but not that these persons describe the same qualities.
In my case, i need to change 2421A dias (JBL 4430).

Titanium diaphrams are stronger, can take more abuse in commercial use,
but some think they can be a bit harsh for home use, unless coated with aquaplas or a similar 'treatment".
I believe Alum dia are smoother, but being a softer metal, can stretch, fatigue and fail.
I believe thats not usually an issue in home use.

I think both materials sound good.
i think too ,-)

I agree with both of you. Either one can sound really good. I think its more a how it was designed issue than the material by itself.

I suppose... though everything else being equal, the Aluminum sounds cleaner and clearer.
Implementation does matter, however that raw material is also critical. Hence Be, Mg, and Al are all inherently superior to Ti... looking at the Periodic Table we can see their relative masses.
Aluminum is soft, but it is actually stiffer as well as being lighter... and that is why it is superior, but it does get brittle due to work hardening and then it can fail.

When talking about materials. Where does the synthetic diamond, that for instance Acuton and B&W uses, fit in. I read somewhere that its breakup modes were even higher in freq, than Be.

Hello Widgethowever that raw material is also critical. Hence Be, Mg, and Al are all inherently superior to Ti... looking at the Periodic Table we can see their relative masses.
Your right but I am think more along the lines of the "Titanium Sucks" school of thought or "Aluminum Sucks" for that matter. I can understand a preference for either and in that case the better material issue goes out the window at least as far as that individual is concerned. I have seen people post that they didn't like the sound of Be drivers as an example.
I see people who switch from one to the other and then you see "there is no going back" comments. To me that's extreme as I find the differences not quite that dramatic. I have Be and Ti drivers running in the same room and I can easily compare the two. Be wins but there is no way I am going to start getting rid of my Ti drivers.
One material may be superior but that doesn't mean you can't make a good sounding driver with the "inferior" material. The audible differences between the materials can easily be lost with bad implementation. I have yet to hear a Titanium JBL driver that I couldn't listen too all the day through. I can't say that across the board.

The mantra is "If it moves, coat it."
Just don't coat it with tar.

Actually, ductile instead of cast would be less brittle!
I personally use cast iron diaphragms with a dusting of undercoating.
Sure, but that reduces the ability to reproduce detail.

Hello 4313BHave you heard how good these thirty year old 2421 and 2441 compression drivers can sound with aquaplasing and biasing?
Well not the alnico's or the 2" drivers. I have run 2426's with Aguaplased and CC networks on a 2344 and that is one nice sounding combination. I used that for a while until I switched over to Be drivers. I like the Aguaplassed 2425's in my 4344 clones as well. The combination of dusting and CC really seems to bring out the best in them.
I have some Aquaplased Aluminum 2431's in the wings that I want to try out soon. Someday whenever that's going to be.

Hey, Heather,
Have you changed your hair-do? Your Avatar looks a little different than I remember!!Take care, and God Bless!
Every Good Wish,
Doc
The only thing that can never be taken away from you, is your honor. Cherish it, in yourself, and in others.
Hello 4313BIn any case, I look forward to your report on them.
Well once I get the LE-14 bases built for L250 the clones I will have a modular bass section I can drop the new top driver set-on. I have preliminary networks designed and they look good in LEAP. At the rate I am speeding along it will probably be late next year.
