I forget if the matter of the paper cone is covered here in the articles section, or if that is on the CRHS site, or on Phil's site. But having read that article, there were a few things (minor though they are) that leave a little too many questions, and I have a page that covers the replacement of the surround- Which with other matters needing my attention, I have been delaying uploading an updated web page that covers the matter of forming the paper cone a little bit better. I hope to have that new page up by the end of this week on my site.
:Need help figuring out if speaker can be restored. I bought it from someone and the cone is definately screwed but I have a few questions about the small coils in the center. Field coil is good..thanx bhedberg21@primus.ca

:Hi,
:At the simplest of descriptions, if the voice coil is still good, it amounts to actually replacing the paper cone with another paper cone, and either forming a flex edge (difficult), or substituting a leather surround. (easy).

The only thing that is not clear on my old page is if you compare the resting height of the edge of the cone as everything is mounted in place (spider is glued to cone, and the spider is centered at this point): The outside edge of the paper cone is even with the edge of the basket where the old surround/paper was glued/cemented.
If your cone ends up slightly off center, or when you trim it you find that the cone was not cemented "true" to the center line of the voice coil form- do not worry as the surround will allow for the differences in tension at higher volume levels, and is not normally an issue. I have seen more than one cone glued off center on new "hi-fi" component speakers, and it apparently had no percieved advers affect on the music reproduction.
:Yeah I read the add and made the cone but it doesn't move as they forgot to explain how to make the edges flexible so the cone moves up and down, which is what I think you were getting at in your post, please send me the info if you have it, thanx
