I bought these wall brackets to mount speakers Edifier (from S530D model). The editing was very complicated because some drawings contain errors (aberrant !!!) and I had to find out for myself by testing several solutions how to fix my speakers. The supports themselves are quite fragile plastic but remain sufficient as long as the media are unlikely to be beaten. The screws and plugs are included with the media. Finally, a rather versatile speaker kit from what I've seen and fully adjustable tilt, but few solid and manual full of errors.
