There is an odds-on chance several of the door-card clips are broken by a previous removal allowing it to flap about.
Two more, again easily broken, are used on the “door-unit”, this is a second internal door card the speaker lives in, and another potential resonant rattle even if the speaker OK.
The inner door unit is mostly held on by M6 hex-head self-tappers and a couple of those were missing when I investigated the speakers in my 25AE.
The door card clips came next day but those screws were on a slow boat from the far east. The local agent might have stock by now. Fortunately I was not in a hurry.
