I use the stand for a 10 kg speaker and I would definitely not recommend putting it in an exposed place. Overtightening the tilt adjustment screw close to 15° does not keep the speaker in the same position during the dynamic test and slides to the stop. Solved for now by tightening the locking screw, tightening the screw in the axis of rotation (8 wrench) and retightening the locking screw.

Pros: With the use of 8 keys, it finally fulfills the expected function, no need to return

Cons: One clamping mechanism for adjusting height and rotation Sometimes the tilt adjustment fix gets angry Needed an 8 wrench for really firm tilt adjustment
