It gave me solution for pole mounting a bookshelf hifi speaker that i own. Basic advantage of the product is that it keeps a distance from the back panel of the speaker, so i have the space to wire them, The only thing that made me rate the 4 stars is that the structure finish isn't perfect in order that the surfaces that you place the screws, isn't 100% parallel with the other half.
Does it's job fine and seems good quality. Having the pole mount on the back of the 804 is not ideal however as it means you have a lot of weight going forward making things a bit unstable. OK if you have sturdy speaker stands but not so good for pole mounting on top of a subwoofer.
