What kind of screwdrivers needed to remove speaker cones of Andrew Jones Pioneer Tall speakers?

Hi All,

A pregnant rat somehow found a way to chew through the bottom most cone of the tall boy speaker. Tried all sorts of screw drivers but unable to open it as we need to take the babies out.

see here:

My son managed to remove the back part and removed the pups...four of them...now need to figure a way out to repair that cone.

Any ideas how much it will cost and do i need to go an authorised pioneer repair person in bangalore or a local guy can replace it with a generic one? as of now sound is fine from the other speakers/cones
