I got a FR159z and I'm replacing the drivers in it.  Apart from having a funny grille, and using non-Phillips screws (along with 4+ different types of screws throughout the box), I'm having a tough time pulling the LF woofer out.  The tweeter no problem, but what is up with this LF driver??

 Is there some trick to it? Or hidden screws somewhere? The front has only 4 screw holes, leaving 4 "blanks".  So the 4 came out no problem. 

I have removed the input connector , put a rod from the back of the driver extending through the connector hole, and hit it multiple times.  And fairly hard. 

The dang thing won't budge.  Either someone hella glued it in there, or there's something else holding it in.

Am I a dope, or what?

I don't recall anything unusual about the woofer mounting other than it used only 4 screws (and I confirmed that with the drawing from EAW...).

My guess is that the gasket has turned into a sealant...  Take a putty knife and work under/around the edge of the woofer.  It might take a screwdriver and a tap from a mallet; perhaps several attempts in various locations around the perimeter.

+1 on what Tim said.

The horns in my boxes can be a pain to get out - the foam gasket really doesn't want to let go when the surface is textured.
A flat screwdriver will usually get underneath and pry it up. Take it slow, and try not to damage the wood or gasket.

That happens with foam gaskets that are used to hold drivers and panels in and reduce vibrations.

Sometimes they need a little "nudge"-sometimes a small crowbar is a good tool

I had some KF650s a while back and had to replace a driver in one of them and I had the same experience.
With some a little time and working at it a little bit, it finally came loose.
It's just the gasket they use.

This goes into the "You just cannot win" file:

At a late 1980's NYC AES John Meyer and I had an exchange about how other "pro" manufacturers routinely ignored the value of gaskets on box openings. Some bass cabs became audibly "gassy" at high levels. (Yes, EAW's name was mentioned.)

Now the use of gaskets becomes a problem.

BTW- a skinny bead of 100% RTV sealant does wonders and allows easy removal of component...
