Client bought them at BB before they called us in for installation. We got stuck with them. The mounting system is by far the stupidest design I have ever experienced. There are no terminals, so when the mounting system snuggly grabbed the connector within the "stalk" that attaches the mount and wiring to the speaker and tore it's solder joint right out, it was an almost impossible task to fix. Had to use the table top stand, which uses and altered version of the same connection point, and tear it apart (it's made of metal, not easy to do while keeping the wiring intact). IT was a giant cluster F$%^. Now the client emailed to say the rear speakers are coming away from the wall. Had to use anchors, but the weight and the angle of the speaker must be too much.
