Dimple in speaker driver cone


I have a pair of Thiel CS 1.6s that have a quarter size dimple in one the driver cones of one speaker that a friends curious child created when he pushed his finger into my speaker (damn him). Can that dimple be removed by moi? Or do I need to have it repaired or replaced by the manufacturer?

Make sure there is no one else in the room and gently suck on it. I know that this sounds ridiculous and I am leaving myself wide-open for major A'gon teasing, but it really worked for me on my old Dynaudios.
Thanks everyone.. I will first try the tape method and see how it goes.

I appreciate all responses.

Thanks UmAlum1990
I have a pair of 1.6s with a dimple just like yours. It ain't coming out easy. I tried the tape, didn't help. I tried the vacuum, didn't work. With both methods the dimple came out but went right back in when pressure was released. The woofer is aluminum and is dented.
I haven't tried Jsaah's method but have my doubts.
I contacted Thiel and the advice was to remove the driver and gently rub behind the dent to smooth it back out. As I don't believe the dent affects the sound I left it alone. I prefer the sound with the grills on so it's not a bother. Good lucj and keep those damn kids away.
