I need to transport these and want to secure them as much as possible, very vague opinions online and nothing concrete from the manufacturer.
Are those just caps or is it the actual screw that need to be tightened during transport? I am able to turn the "caps" and can feel them tensioning up..
Some suggest finger tight plus a 1/4 turn :nfi:
Owners manual on the 801 Nautilus refers to a "transit clamp" while 801D Schematic drawing shows this as an "access plug cap"
From another forum a claimed response from B&W:
Apart from in the CM6, our FST midrange unit has an unusual mounting arrangement. The driver is mechanically isolated from its enclosure, whether it is the sphere / tube "head" or a more conventional cabinet, by flexible gel components in the fixing arrangement. To optimise the isolation, a single securing rod is used that runs from the back of the driver to the back of the enclosure. The tension on the rod is controlled by the large head straight slot screw at the back of the enclosure, and this in turn controls the pressure on the flexible gel parts. In order to prevent excessive movement of the driver under impact in transit, a clamping disc is fitted over the screw head, held in place by a cross head screw in the centre. On installation, this clamping disc and centre screw are removed in accordance with the pictorial instructions on the label fitted to the assembly.
It is important that the tension on the rod is set correctly. It is preset at the factory and should not require adjustment, except if the driver has to be removed for one reason or another, but sometimes it may get altered by mistake. This may be because one's natural instinct is to have a fiddle to see what happens, but occasionally removing the transit clamping disc has been known to loosen the main screw if it has bound itself in the thread.
If either of these has happened, refer to your local B&W dealer to have the tension reset correctly. We recommend that you do not attempt this yourself.
