Support used to attach to the wall of Triangle comet Rear satellite speakers of a home theater. Given the weight of each speaker (8kg, size (40x22x28 memory) and the price it was a solid support. And I am not disappointed. Construction seems serious. I fixed these two media in brick plasterer using 4 ankles Crampon brand in lieu ankles supplied in the pack. (80kg per fixing point in this support should take it) I hesitated with support of another great brand that tightens the enclosure between the front and back but it did not seem well suited to my model that features a curved front and a grid that goes down very down. The carrier BT 77 tightens meanwhile the enclosure on the sides (which are parallel in my case). Some small adjustments are necessary to center the speaker and then tighten the 2 side screws after inserting a foam wedge delivered with. I have inclined support at its maximum on the front (7 °). The back of the enclosure so slightly off the support. To avoid this problem and also to reassure everybody, the support has 3 holes that allow in addition to maintaining the enclosure with screws. But there must be drilled enclosure ... I have not used the 2 side holes (drilled on a face bothered me a bit if one day I pulled the support). I only used the bottom almost invisible hole plate perfectly the back of the speaker to the stand. However, I removed one star because the HP original thread remains visible output wall. In my case it was not too bad but some want a more discreet wire. But I think that a little tinkering can hide (the top tube opens to the back of the stand against the wall. It would suffice to provide an output on top of the tube just behind the enclosure. ) The implementation of this support is very fast. Skip HP son in bulkheads much longer .... Delivery Amazon perfect and very fast. Competitive price.
