repairing ppi 356cs

my speaker recently began sounding distorted and quit all together. i removed the panel and took it out. the cone flexes well and comes back to the original position when pushed on. there is also no burnt smell of any sort. there ar eno tears and no visible 'breaks' in the structure of the speaker. when i turn on my system and lightly push the surround or cone, sound comes out. online searches that i may need to fix the tinsel leads. since i'm no expert in this, i have no clue on how to properly take it apart, then repair it. and i can't even see the tinsel leads. aside from repairing it, can i place foam pieces (maybe 2 small pieces) on the surround (see attachment) and have my door panel push against the surround so the leads connect? or would that do more damage than good? and how bad is it for my system to have one speaker not playing? and how badly is it for the speaker to randomly come on b/c a bump in the road causes the lead to connect?

The tinsel lead of that speaker is glued to the spider.  This is going to be a difficult repair.

to clarify, that diagram is not my specific speaker. i just needed something to show what the surround is. but are all speakers of that design as shown in the diagram?

i am an idiot wrote: A tensil lead is a small braided wire that connects the speaker terminal (The place where you connect your speaker wire) to the cone of the speaker.  Find the tensil lead and inspect it for damage.  If it is damaged AT the terminal, it is usually an easy repair.   If it is damaged AT the speaker's cone, not so easy.   Whatever you do, it can not be shorter than it was originally.  That is why it got damaged.  It has to be extended at least a little bit.

thank you for the advice! i absolutely love these speakers and really want to repair them. however, if anyone has suggestions on comparable speakers to the PPI 356CSs, please let me know.
