Any tricks to remove drivers from a (sticky) cabinet

Buy a set of mechanic's picks like THESE. Remove the drivers by working them loose with the picks, gently pulling from behind the screw holes in their baskets.

Install a pneumatic valve on the rear of the cabinet.  Pressurize the cabinets to 35 psi.  Grab some popcorn and enjoy the show.

non-sealed cabinets will require a little extra creativity.  Duluth Trading Company briefs stuffed in openings seem to provide the “correct” balance of mass and density.

or, just turn them upside down and shake them.

The show will see would be the driver cones popping off the speaker frame.  It is fairly easy to use the screw method with vise grips an a piece of wood as a fulcrum, and there is very little chance of damage if you have someone to hold the wood in place.

This was my attempt at humor.  Guess some people are better at telling jokes than others.

I'm an experienced builder/servicer involved in performance upgrades.  Yes, working with the holes in the frame does lower the drama and incident of involuntary speaker cone and/or cabinet modifications vs prying on the outside of the frame.  Engaging a couple of threads on a bolt/screw seems to do the trick -- every time.  

Thanks for the instructional video. 

I know you were kidding.  I did like the idea, but, I just thought it was an opportunity to again push the safest way to do this.  I saw the result of an "accident" at a dealership where the driver was being pulled from a $30,000 pair of speakers and the front panel was gouged (a speaker without a grill cloth).  The result meant ordering a new pair for the customer.
