What a pity !
the ogival plug I don't care, but the rip is scary!
I don't know if glue would suffice, if the structure is damaged (fragile)
there will happen some nasty resonances that will be audible.
Try some glue ...

I own original intact membrane but I need it to outbid

If you know how to remove the original glue
And do the rest of the job ( voice coil former , the wires , centering , glue it
to the spider ,then the external suspension )
Here , a professional worker takes 40$ per hour

how to remove glue? acetone?

They look a bit like the Kevlar midrange drivers in my B&W's. There's very little cone movement on a mid so you might get away with patching the rip. Its not my field of expertise but I would perhaps be looking at some fabric "pasted" over it using something tough but slightly flexible to glue it. Polyurethane varnish maybe ?

So are the speakers bowers

The yellow woven cone looks very similar.

I don't really understand what you are asking. You either have to repair them, rebuild them or replace them.

Official B&W service manuals are widely and freely available on the web... just do a search
