I feel your pain.. I hate everytime a new scracth shows up on my new car or speakers. I would try the ice cube in a bag trick. Cold metal contracts and may pull that dent out. Worth a try.
Thank you man, you're kind. I'm otherwise notorious for having heaps of very old stuff that looks out of factory new. I don't even try, it comes natural to me. Even I only noticed when my friends started teasing me. And now I've marked something I wanted to outlast me.
This is the deal; the dent is very small, I say it again. I don't even think it would react to ice. I know where it is, but every time I have to spot it first.
This is also a curse of a sort as it makes you really believe this could be fixed with no traces left.
I'm still thinking how exactly to do it, trying to foresee all possible hick ups. I'm waiting for KEF to write me back, I've noticed rubber covers can't be removed without damaging them. I want to see can I buy a set from KEF directly.
When removing screws from particle-wood and MDF there's always a small damage. That's why I plan to release the entire baffle. The baffle is curved which would mean it will rest on the driver's edge when placed so that the back of the baffle is visible. I must find soft resting material to put under so that the driver doesn't touch the surface.
I have to mark all the wires as
@Swerd said. And then simply apply even softer touches from the inside to prevent merely bending it the other way. It has to gradually come back to the point where it can be detected any more.
I'll keep strategizing while waiting for KEF's e-mail.
