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.

Hi Sean, I dunno, that was what I was told. I justified it when looking at total Q. The electrical Q seemed to have a greater impact on Qts than the mechanical Q did.
Anyhow, does this bamboo material driver look like a good choice? It retails for about $35 each. I can't put up response curves but above 14k there is an 8db plateau from 15-18k - that doesn't look very musical or accurate to me.
Cdc: I've got to head out to the ear doctor and then off to work. I'll try to explain why Qms is important later tonight. What i'll have to say is controversial amongst most speaker designers / engineers, but the facts present themselves once one does research on the subject. Even so, many that are rooted in their beliefs refuse to see the light, just like those that told you that it didn't really matter. Sean

I spent quite a long time typing out a very thorough yet somewhat easy to follow response to the above about Qms, loudspeaker design, resonances, the amplifier / speaker power transfer interface, etc... While attempting to perform another function on my computer, i somehow managed to shut down multiple windows at one time. One of those windows was the Agon post i was working on. Needless to say, i'm quite frustrated and not up to trying to re-do it right now, so it will have to wait. I apollogize for the delay and will try to get to this soon.

As a side note, good news from my ear doctor today. He told me that they can stay on the sides of my head, no need for removal as of yet : ) Sean

El: I don't know if that was meant to be humorous as a comment about modern day technology and how things get "lost in the system" or to say that i'm bullshitting and didn't do any of the work i.e. an excuse. Believe me, i invested a great amount of time in what i lost and it doesn't make me happy. Sean
