Westend is right, and that is what I would try first. Some of those types of stereos also have that keyhole like attachment to hook the speakers to the side of the stereo main unit to make the whole unit more portable also, but lifting up on the speaker is still the key to removing it. Unfortunately though I've seen several of these types of systems glued in place too. My RV had the satellite speakers hot glued to the cabinet so they wouldn't rattle. This was done by the manufacturer. Actually damaged the wood behind the speaker when getting it off, but thankfully the new speaker was a bit bigger so it hid the mess. Of course when I was putting the new speaker back in all I did was use 3M double-sided tape, so I guess I'm almost as bad.
