Okay, fellas, help me out here. True or false:"All other things equal, a black color speaker cone will sound better than a white color speaker cone."
"Quantum informatics has important implications for high-end audio."
Thanks in advance for your opinions!
Follow Ups:
...that speakers will someday be judged on the content of their sonic character, and not by the color of their cone.
LOL From Dr. Martin Luther Jr.'s famous "If I had a hammer" speech?
I'd stammer in the eveningI'd stammer all over this f'n land
[The film takes place in New York City, a few years after the original film, wherein Billy Peltzer (Galligan) had acquired Gizmo (voiced by Howie Mandel).]
but white dots on black cone is great for blh
repeat after me
it was an itsy bitsy teeny weenie yellow dotted polka bikini that she wore on today
ahh shadap your face
I dunno Christopher, those comments seem a bit too cryptic to yield much information. Gets us thinking though, so what the heck.At least with the old JBLs, a white cone indicates that a black cone has been sprayed with Aquaplas. This results in added mass as well as presumably greater self damping properties. I have heard some mighty fine sounding Aquaplassed cones, such as the LE-8Ts in my old Lancer 33s.
The slurry from which cones are made is likely tan colored due to its wood pulp origins. The black dye or stain is an added component. As cones age and are exposed to UV they tend to lighten, sometimes back to a light tan color in the case of 1930s and 1940s speakers. The paper has usually weakened as well and will tear easily. A cone in this condition would have very different properties than a spankin' new black cone, but is generally worth much more to collectors. Hmmm.
I asked this very same question many years ago to different speaker manufactures.
It depends on the cone material. A cone like a Lowther, which uses wood pulp among other things- yields a very thin, hard cone. The cone is rolled to increase stiffens. that is why there is a seam.
Bleaching the cone weakens the fibrous material.
Bozack used a mixture of paper pulp, and wool. Then dipped the apex of the cone in lacquer. I was lucky enough to see this in person.
JBL and others uses fibers that are used in kevlar. that is why they have that grey look.
Advent used a mixture of garbage bags and paper the orange Advent tweeter.
Banana fiber ( Fostex and carbon fiber has also been used.
JBL also used "Lans-a-plas" a urethane foam cone to both stiffen and dampen cone . the Le 14a is a near perfect design using this technique.
RCA and Western Electric used phenolic.
I think the Yamaya MS 10? White cone nearfield monitor was done to “look cool” and others copy it.
Today though, perhaps there is a white cone which is OK. You don't see it in pro stuff though.
Others have used aluminum ( Leak, Community), which is a sandwich cone of a skin of aluminum and Styrofoam.
There is also a UV issue in white cones.
My own feeling for white cones is the same for white bread—keep away!Of course the car speaker is in their own world.

Since the black in the black cone is likely to contain carbon, it will have some ability to absorb ambient noise.Joe Cohen
for a compromise...
although it looks white in this pic.
FE126e gets to 100dB/1w at around 7kHz, but thats the worst bit.
Very nice mids though.Philip
Christoff - where did you get that crap from?
"Quantum informatics has important implications for high-end audio."
Sincerely i am interested, i worked in math & computer science
and there are pseudo-scientists trying to sell their crap
by any means...
Vince S, I am pleased to report that the opinions I quoted are those of a private individual and not from someone in the employ of an audio manufacturer's marketing department.However, what is interesting is that this person does have some truly brilliant and innovative ideas for audio. For most of these he is able to provide perfectly rational explanations.
I have met more than a few people like that in audio. Some of the most brilliant and creative guys, who can build things that inspire admiration and even awe, also have a few (or sometimes more than a few) irrational ideas that seem to border on the occultic. And of course there is a large gray zone in between where I am willing to give people the benefit of the doubt (at least as long as it doesn't involve me pulling my wallet out of my pocket.)
However, maybe we shouldn't be too hard on them. Some highly respected scientists have also, despite (or perhaps because of?) their far more advanced and rigorous educations, come up with some speculative theories of the nature of the cosmos about which we could say the same thing, although perhaps most would be more charitable and simply point out that the theory leads to a paradox, or some such thing. In fact, some of the bizarre stuff we encounter in audio is probably, at least in part, a result of some ordinary Joe reading some of these far-out cosmological theories at the bleeding edge of science and being a bit too impressed for his own good.
I'm grateful to the eccentric audio geniuses around me; because of them my music listening life has been enriched, and I just shrug my shoulders at the stuff that gets a bit too bizarre for me to process without huge leaps of faith.
And as for the people who spend the entire inheritance from their rich uncle on audio "snake oil," while I feel sorry for them at various levels, there is also a part of me that says anyone so gullible should be just left in peace to enjoy the ecstasy that he found by listening with a $10,000 magical tuning pebble (blessed by the Dalai Lama himself!) inserted into each ear . . . and of course I also sympathize with the umbrage that people like you experience when you encounter the more egregious audio snake oil salesmen.
The famous one.

Hi DJKCan you give any clue,as to what is happening in each of these two cases?

There are three constants in life: death, taxes, and the inevitability of a (speaker)wire thread being closed -SY
Only if it has an Alnico magnet and the white one a ferrite.
I worked with a guy that actually thought that painting a room black made it quieter.
The irony was he worked at a laboratory which did acoustics and he still had a hard time accepting the truth.As for his statement, if the cones were exactly identical in acoustic performance it is still possible, if the listening comparison were done sighted.
As for "Quantum informatics has important implications for high-end audio."
I would say it is utterly true that this message would be spread far and wide….if you have a financial interest in a company trying to sell with dazzling words.
Goggle search “Quantum informatics” and see if you can figure where it would be so important to audio, unless its some advanced copy protection scheme.Where did this steamer come from?

> Where did this steamer come from?I'd rather not say, but I wouldn't be surprised if my source is a friend of a friend of the black room painter you mentioned.
Yeah, I did a quick Google of "quantum informatics" and the top site was the math dept. of some university in Russia, and they gave the example of using it to develop an encryption scheme where it would be impossible for someone to break the encryption without revealing themselves in the process. Very interesting, but no tie-in with loudspeaker dynamics could be seen.
Funny thing is, I don't see how all other things could be equal if the cone colors were different. Different colors would be produced by different compounds with different inherent physical properties.
I'll try anything once -- if someone else is paying for it and I can listen in a double-blind A/B test . . .
Ok for info.
Quantum computing is nonsense to get research funded.
It is a trend and they are many academic in it.
Actually it is extremely poor.

It may be a matter of more aural sensitivity
with lack of optic input (more brainpower
available to hook up to the ears).> "quantum informatics"
??????.....Quantum physics perhaps.
(wherein the observer is part of the phenomenon)I think most people (sighted) may think a black
cone to sound better than a white one. Something
more 'professional' looking about black.
(simply because most cones are black (or close))?
I just got some clear plastic cone drivers that
don't 'look' like they sound as good as equivalent
black plastic cone drivers.......:)
But if i told you why i'd have to have someone shoot you.
