Purchased 9 months ago, they support my Dynaudio BM12a all this time without any worries. the base is heavy, the assembly is serious, height adjustable. The top is a bit small, my bm12a are a little big blow but it's not very serious. I put the spikes on the plateau and set a plate of aluminum underneath my speakers with a double-sided tape, good insulation, low vibration.

For me it was essential to develop because I work in the middle of my room, glued to the wall, it would be too far away and I had much too low.

voila: practical, serious, tough, not very expensive (€ 140 bought in pairs) still no problems with k & m
