The drivers are inconveniently glued in place, but can be relatively easily removed with some elbow grease.

I used an iOpener to soften the glue, along with a Jimmy and metal spudger to score the glue around the circumference.

Each driver area has a cutout section, as indicated, which will assist you with prying out the driver.

Try to work the driver out only by its sides. I pushed my metal spudger underneath and pried upward and damaged the driver grille.
