I did that before and someone told me that you are rubbing the cone on the voice coil or something and it is terribly bad for the sub.

It only happened on mine when i pushed down on one side only. If i pushed down on both sides evenly it wouldnt do the noise.

How is it bad? J/W not trying to argue, I have always wondered (sp) if it was bad or not

You can easily damage the soft parts/motor if you are not careful.

And it could possibly be that you are pushing at an akward angle and the former is not traveling down the cylinder in a straight line, causing something to rub. If you have to push, ensure you are pushing STRAIGHT down. If you still encounter the grinding, then something is wrong.

just the coil rubbing on the motor

push it even and it wont do it

check the coils with a dmm if you want assurance
