The Dynaudio Contour 20s come with a factory stand that bolts into the bottom of the speaker cabinet. The stands are built very heavy, but I filled the open tube portion with sand to add more weight and stability. They are hard to move now.
Same for B&Ws I use in AV set up. I invested in the factory B&W stand; better build and weight. Set at best height for optimal tweeter to seating position. Again, filled open tube with sand.
Several aftermarket options are available, but worth investing in better ones with more stability and weight.
