I tried removing the woofer from one of my M3s, no joy. The driver practically fell out of the M40Ti when the screws were removed, this one won't budge and I'm afraid of damaging things if I force it too much. Even tried removing the tweeter and pushing from behind, its completely stuck.

One odd thing I just noticed, the M3s look like they are veneered on both sides of the MDF(!). Not sure what the point of that was.
