Put the large silver piece back on its part of the midrange. That is how the driver is mounted. I'm surprised it didn't fall out.
Simple B&W Nautilus 804 Question
I just purchased a used pair of B&W Nautilus 804 Speakers. I am in the process of unpacking them. The seller is not available to ask. The instructions mention a transit clamp in the back of the speakers with no other notations. Is that the large screw like metal thing protruding from behind the top Kevlar driver? If so, do I completely remove it, or do I just loosen it. Thanks in advance for your help.
