Leave it alone. Besides risking damaging the cone, I understand that you can break a fragile plastic ring around the grill, and you won't be able to put the grill back on.
Safe removal of tweeter grill on B&W 801 Series 2
Has anyone had experience in removing the small grill cover on the tweeter of the B&W 801 Series 2? To tighten speaker cone screws, I easily removed the other two covers but the tweeter cover seems held at the bottom, somewhat wedged in by the small brace. I am reluctant to force it for fear that I might inadvertently hit the small tweeter dome. That would be a bad thing. All of screws, by the way, were much looser than I ever expected and the tightening brought much improved sound. Thanks in advance for any comments.
