Questions about InLine Speaker stand telescope

Hi, I changed to a Samsung Q990C, I was able to put the satellites on it but it's too light as mounts, it's not very stable and you have to buy the appropriate screws separately. I think I should go for a stronger model, as it's designed for smaller, lighter satellites.

Unfortunately, these speaker stands are not compatible. In this case, I recommend using Bemero SMS-9040BK (1 pair, stand, height adjustable).

Yes, this item is compatible with the Bose Surround. :)

This system is intended for speakers with a screw thread on the back. This product contains two brackets.

There are two supports.
