Hi,
as noted in the previous post by shadders, the thing to do is to try it. -if it sounds OK to you, then all is well.
I am not familiar with these speakers but I understand that they are studio monitors and are fairly heavy (- maybe about 17kg in weight each speaker). If this is the case the monitor arm would have t be well chosen to support this kind of weight and you may be better off searching for more substantial supports - can you find anything online on specialist seller sites maybe? (I am guessing that you have ruled out dedicated speaker stands, but these would probably also give you better result., if you have the space.
