Speaker rebuild question

Hey everyone

I have old Volvo 850 rear door speakers, which are blown, and i wanna rebuild them

I've found some cones made of 'carbon fiber' or polyurethane, can they be used instead of blown paper ones? Also - which glue you'll recomend to use?

But I have another issue - old tweeters - they have broken plastic, and i couldn't find anything looking close to them(Photo of tweeters bellow), or their type on market, but I've found some 'close variants' on aftermarket speakers, but i don't want to destroy other speakers to rebuild mine.

Any solutions ?

p.s. I'm newbie, or rather, 'noob' in this theme

p.p.s. Tweeter top size is around 47mm, bottom - around 15, height around 45, and bolt width around 3mm

Buy another set at a car breaker or car repair shop.
Ask around, you may get lucky.

It is a lot of work, needs experience and dexterity to get good results.
You need cones, coils, coil forms, glue, and also tinsel wire, and must be able to center and fix the coil in place.
Not for everybody to be able to do, particularly if it is done once in several years.

In my city, there exist several speaker repair shops, and the cost for 6" paper cone speaker repair is about US$1.50 for which I get a new voice coil, new cone, and a check of magnet centering, which is extra if work is needed.
If such a facility is available, use it.

Thanks for the answer

In my country it's little bit diffrent, and becuase of that - I have only one guy who has some parts for speakers, and those speakers i got for free from him, and I don't have any shops who can fix them, maybe i'll try to find speakers somewhere else.
 
Do they have weird dimensions?

Personally I would just try to get good sounding fresh ones which fit those holes and available space, and call it a day.
You might have to make adapter rings to fill small gaps if any.

By the way, where is: "in my Country"?
Suggestions depend a lot on location.

EDIT: just watched this

Forget about repairing that broken speaker, reusing tweeter, etc. , you´ll spend 10X the straight replacement cost.

Just get a same diameter replacement speaker, paying special attention to screw hole placement aand call it a day.

Worst "problem" would be that they seem to be mounted inside a plastic "bubble" ; you may pry it off or cut it around with a Dremel and mount/glue it to new speakers.

The problem is that yes, they are specific, and need special mounting brackets for aftermarket speakers, also, as I heard, factory rear speakers are sounding best among many others, but i'm not sure
