'dimple' tweeter fix

I called dynaudio, they do not recommend vacuum cleaners, too much suction. They recommended a combination of scotch tape and suctioning with your mouth. Worked perfectly for me on a pair of audience 40's

been running music on the SE and I found that something is amiss with the sound (can only hear though on some recordings-- crakling like sound :( ).. Does anybody have any idea what are the chances of damaging the tweeter or how are tweeters arranged in sequence..

TIA

The question I had was once you're able to pop it back is the tweeter damaged even though visually the tweeter looks ok
Are sonics effected once the tweeter is pushed in

You won't know until you listen to the popped back tweeter (driver).

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.
