I use the supports for my "devil Consono 35 Mk3" - weight per piece 1.3 kg. The attachment is on the ceiling (rear speakers). The attachment to the box was great - bolt through the round hole and the cable through the long (that devil uses larger M6 screws and this is not supplied beyond the control of the holder). The configuration options are good - the strength for this purpose OK. At first I am afraid that the holder under the weight of 1.3 kg gives something - but if you just set one tooth longer fits the And please note that this statement that I have the speakers mounted on the ceiling -. So the burden comes to the holder CROSS. In this type of installation the holder coped but probably none 6 kg.
