It happened to me before, but it was soft dome in a pair of Dynaudio. Tape or vacuum both worked great, but I always wondered about the sound afterward even though I could not hear the differences. Dynaudio Esotar T-330 claimed to have multiple coating on the dome to create the dispersion, so a sticky tape will for sure remove some coating, not?
