Suitable for speakers up to 20kg.
Note that for our ZX1 speakers (which weigh less than 20kg), we advise using a medium or heavy duty speaker stand not a light duty one. The stand spigot hole in a ZX1 is offset to the rear of the speaker, so the speaker sits out of balance on the stand. The lightweight stands have a greater tendency to fall over with a ZX1 on the top, whereas our heavy duty stands are much more stable
