Of course, you have to pay attention to the size of the speaker so that it still fits between the clamps. The holes for attaching to the wall are 10 mm, so I attached it to the concrete wall with 8 mm anchor bolts. It should be taken into account that these things themselves are quite heavy, so they must be attached to the wall very properly. Otherwise, a good and high-quality item, well adjustable and stays in the adjusted position. I have relatively small speakers attached to them, so they are also far enough away from the wall, which is important for sound quality. It pays off, for example, when using it at home, where saving space is important. I like them and recommend them to others.
