Hello. There is a question how to fix the driver during the measurement of parameters. The driver must be positioned vertically in the air. The question is how to fix it correctly? Intuitively, it seems that the driver should be fixed through the holes in the basket that the manufacturer made for this, to some kind of structure that can hold the driver so that there are no obstacles around the driver. But on your videos and pictures, the driver is fixed by a magnet. In some cases, there are solutions when the driver is fixed to the housing by a magnet, and the basket is fixed in the hole by pressing. But in most cases, the drivers are fixed to the case through holes around the circumference of the basket. So how to properly fix the driver so that there are no parasitic vibrations during the measurement?
