Speaker Cones: What are the differences?

[roshi]

So I've been looking at hundreds of different speakers, all with different type of cones, made out of different materials. There are the paper cones, the ones out of different metals or even Kevlar. Now people always bash bose for using paper cones, but many other companies (including ones people like) use paper cones too.
So what is really the deal between the different materials?
Thanks!

EDIT: I realize I put this in the wrong category. Couldn't find where I could delete the post. Sorry...

There are paper speakers that are good, and there are bad ones. There are polymer speakers that are good, and there are bad ones. There are Kevlar speakers that are good, there are bad ones...etc. It really has to do with the complements. The cabinet, x-over, drivers, perspective possible room sizes all factor on a speaker's performance.

There is a huge difference between Thiel's paper drivers and Bose, massive.
