Damage tweeter - Repairable?

[gort]

Bought a pair of Q acoustics 2010i speakers and one has a damaged tweeter (appears damaged in transit.)
Looking for a fix first rather than a faff of posting back etc.
It's quite noticeable when in use and have done a 5000hz audio test (YouTube vid) and the tone is quieter and muffled compared to the tweeter of the other (undamaged) speaker.
Question is... is this likely repairable?
I've seen the vacuum cleaner suck trick amongst other but they focus on the actual dome bit, this is mostly the edge which seems to pushed in and damaged also.
Could try the vacuum or stick tape trick but don't want to rip it out!

Thanks all for the quick replies!
They were fairly cheap 2nd hand so thought I'd consider a fix and ask first.
A new tweeter is more expensive than the speaker cost.
However, given the risk of possible underlying problems and making things worse if I try to fix it, I think I'll request to ping 'em back!

Ta!
