PVA (woodworking) glue is best for paper, you could glue a cigarette tissue paper over the tear on the rear of the cone for strength.
Impedance varies with frequency, use impedance plots of your drivers and make crossover calculations using the actual impedance of the driver at the crossover frequency

I have successfully repaired many paper cones, using SOFT cure flexible glues ( ie Alene's Super Tacky or Roscoe Flexbond )
The PVA wood glues ( Elmer's etc ) dry hard, and inflexible and after time get brittle.
If necessary thin black tissue paper ( available in craft store ) can be used for reinforcement.
I have also used thin clear RTV glass sealant.
( Toothpicks , a pin vise, and dental picks come in handy )

Any wood glue PVA where the stuff left around the cap is always
flexible is the right stuff for the job. With no part of the cone
missing a near invisible repair is possible. Use a toothpick and
apply to wet the fuzzy torn edges only and remate the tear.

Alternatively use the search facility.
