I ordered these for a pair of Definitive Technology SR-9040 surround speakers that only come with a keyhole bracket. There is no way to attach these mounts to this mount. certainly not in any way that allows you to use the ball joint to point the speakers downward. So they go into the wonder basket (where I keep all the gear that could ever find use). If you're considering buying the DT SR-9040, do yourself a favor and get the 9060, which has respectable speaker mounts. . You will thank me later.
