I just purchased a pair of B&W 801 SERIES 80 speakers and I have a non working tweeter on one side. They both worked before I moved them so I want to check for loose wires/ corosion on the tweeter connection. I took the cover off and four small allen head bolts but it seems like it is pressure fitted at the bottom. It is really tight and I have try to pry, pull (and everything else) to no avail. Can anyone provide some insight as to how to remove this tweeter without causing damage? Thanks
