Paper Cones in HiFi?


I may be naive or uninformed but I've noticed several speaker mfrs using paper cones in speakers priced over $2k (ie Vienna Acoustics Bach and Sonus Faber Grand Piano). I always thought paper cones were for low end Radio Shack speakers.

Can some please educate me.

Thanks.

Hey Marco.

Those headphones are sweet!

I think they would look great with a head gear orthodontic apparatus.

I dont know if you are joking around or not, but they look truly rediculous. They look like they might sound kinda "Tinny" HAHAHHAHAHAHAHAHAHAH

Anyways, i guess if they sound good....
i think i will stick to speakers. :)
The majority of audiophiles prefer paper over other materials due to its "natural" sound...however...hi end speakers with paper drivers are often coated or a poly-blend...hence no relation to lower end speakers...
I have a pair of S.A.P. J-2001 speakers that have two 12" paper cone woofers. While some may view paper cones as "old" technology, that does not mean it is inferior in any way. This speaker also has a horn midrange, but the compression driver has a titanium diaphragm ("new technolog"?). Both the woofers and the midrange utilize old fashion Alnico magnets. I believe the designer utilized what works best, not what is fashionable and current. At about $22k, I don't think the "cheapness" of paper was a consideration.

A friend of mine spends a small fortune collecting as many Western Electric or Altec paper coned drivers (515 or 555 or something like that) as he can get his hands on. The cones are so old they crumble if touched. The sound, however, is very lively and articulate when these drivers are used in his full-range, multi-driver designs.
Paper is a low mass low loss material. Paper cones have better transient reponse ang higher mechanical Q compared to plastic/polymer alternatives. They have higher efficiency. But they may have resonances which must be taken care of at crossover side. The envoiremental robustness is achieved by surface treatments. But since it is a compressed material it will loose it's structural rigidity in time. High tech marketting jargon can also be applied to parper cones by giving exotic names to pulp mixtures etc.
Reinforced paper cones seems to be one of optimal choices, dont know to which extend slicing the paper etc. is just hype... ?
low-end would be poly-propylene materials... it has a smoother and deeper (comparable to paper), but clearity and precision is very bad - PP simply flexes too much when playing bass, making distortion the rule rather than the exception. Surprisingly many manufactures markets their pp cone woofer as quality - showing of their smooth response curves and low-end fs values... and only very very few gives you any idea of rated distortion and power compression, which is much more important in a bass unit.

from what I've heard aluminium is not optimal when it comes to timbre, i.e. it makes the sound less natural, and Kevlar tend to have a less uniform response curve than paper, but have a deeper fs value, ideal for non-vented enclosures, but who uses that for bass?
Anyways the point being that its a trade off (between many things, where paper still seems to posses the best of each.

I myself have two 15" paper cones - one $50 that sounds like crap compared to my $500 JBL 2226 G 15", but that would be expected - paper cones comes in many varities too...
