How do I remove the woofer from ads 300 speaker?

So I found a pair of ads 300s at the take it or leave it section of the dump...I mean solid waste disposal and recycling center... along w an NAD 2200.  The amp and one of the speakers work just fine, but the other appears to have a bad woofer.  No sound from the woofer (tweeter is fine) and when I gently push in on the woofer cone it scrapes a bit.  However I can't figure out how to get the darn thing out.  I removed the 4 screws folding the metal frame to the baffle, but no dice.  No apparent way to remove the terminal cup on the back either.  Google has been no help so far.  Any ideas?

Also, try putting an awl or something inside a screw hole, and see if you can leverage it to help separate the woofer from the frame.

Can you remove the tweeter to access to the back of the woofer?

Try finding a machine screw that has the same diameter of the flange opening screw holes. Use that as a jacking screw.

I use this method on my Alon woofers and it works great, won’t bend the driver frame or damage the wood.

If the above advice doesn't work, is there a piece in back holding the speaker terminals that can be unscrewed and moved aside so you can push the woofer out?

It’s stuck.If you remove the tweeter you may be able to push it out from behind. If not, get 2 flat head screwdrivers and wrap the ends with some electrical tape. Spray the ends of the screwdrivers with some silicone and gently work them in between the speaker and cabinet 2 to 3 inches apart from each other. If the drivers are stuck to the point of bending the speaker, try different spots.

If you know for sure the drivers will be replaced, another method would be to get a razor and cut around the outside edge of the cone. Then you should be able to get your hand inside the speaker and pull it out.

When the speaker goes back together, be sure to use new foam surrounds. I’m guessing they should be around $20 for a kit that does both speakers.
