It is well known that the screws of the loudspeaker chassis loosen with time. This is not good for the sound at all.
It's also known that after very tight they come loose, so be careful. To make this perfect you should get a torque wrench.
Good are the ones from Hazet, among others. I prefer to use one that is like a screwdriver, because you have more feeling here than with a ratchet. See also here:

There are three possible settings on the key:
1. to Linn with 2.0 Nm
2. according to users (forum) 0.6 Nm (3k-Array)
3. my favourite so far 1.4 Nm
I have always heard with 1.4 but many have recommended 0.6, so I tried that. First the Linn recommendation of 2.0 to 1.4.
That didn't sound very good, it sounded sharper and less sound. To hear 0.6 I loosened all screws, again be careful not to unscrew them too far (not out of the thread).
Then I waited a few hours to let it all settle down again. That means for all those who have more than 0.6 loosen the screws and let the material rest for a few hours.
You can also listen to how it sounds with loose screws so you know how important it is.
I have to say 0.6 sounds really good, many thanks to those who passed on this tip! I will listen to this for a few days and then test 1.4 again.
Previously bad recordings sound just great. My God, the instruments and singers sound authentic, they are standing in the middle of the room.
First of all, we tighten the drivers of the tweeters, always crosswise. After the first tightening I would go through them all again to check that the torque wrench clicks.
For the bass we first have to remove the ring. Linn left a small notch in one place, but it's hard to find. I once bought a kit that allows you to remove the ring without damaging the paint. See also here:

The lower bass on the Akubarik can be tightened with a ratchet as a torque wrench. You should use 1.0 nm here, but I am still testing.
IMPORTANT: Many torque screwdrivers are advertised with the in/LB scale which can be a bit confusing and most of these are for higher force. Please make sure you convert it to Nm scale.
