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.

If you're referring ONLY to the black plastic cover plate with screw on the upper back of the speaker, remove it. Its function is to protect the portion of the midrange driver (which protrudes from the back) during transit.

Still need more help. I have removed the large silver color screw, that is all. There is a big black plastic ring around where the screw went in. The manual sais the instructions are on the back of the speakers. Obviously removed. Must be when from the factory.
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.
The manual (for the 800) states that one should remove the cross-cut (philips driver) screw which is for transport. It say NOT to remove or adjust the slotted (flat driver) screw which tensions the midrange driver.
