I have some very similar ones (millenium) from thomann - same pole and top, slightly bigger bottom and I do NOT like them. I have quite thick soft carpet, so i used the supplied spikes, but at the extended height, they wobble side to side if pushed. my exit route means going past them and i have caught falling speakers multiple times, and one time catching it, knocked over a monitor, breaking a key on my controller keyboard. In my room I need them, so i am just being as careful as I can. If you would not touch them they are great. It's just that when set high, even with the spikes, there is wobble if prodded.
