Once a soft dome is deformed with a crease, it no longer behaves the same way under operation. What likely occurs are deviations from the original frequency response above 7000Hz where the dome typically starts entering resonance modes. The deformations and creases that might be in the dome now will alter those modes and change the way the tweeter radiates.
If you can quickly correct a poked in dome so that there are no creases, you stand a better chance at an unaffected speaker. If it hasn't been corrected for a length of time and creases permanently establish themselves, your best bet is to replace the dome assembly, which in the case of Dynaudio, an expensive proposition.
