As a sound artist, I build installations where I need to put speakers in different places in the space. This wall mount comes in very handy and gives me a lot of freedom to hang the speakers safely and quickly. I use them with both the Genelec 8010 and the 8020. I've used them to hang speakers on the wall, from the ceiling, on slanted surfaces and even poles. It's also easy to mount them to theatre clamps which makes working on a theatre grid very easy and quick.
So, a great, versatile, mount that even very cheap!
