What is the purpose of the black plastic surround that comes taped to the speaker? Is this supposed to be left on the speaker or removed after install?

Asked by: MechEng
That "plastic surround" acts as a protection for the speaker from packaging and shipping hazards. You can remove that plastic once the speakers are installed.
