A:AnswerThis mounting bracket is designed to attach to drywall with either hollow-wall anchor bolts or to a wall stud with wood screws. I am doubtful that this would screw into a pre-wired wall plate. It is possible that it would, but is not designed for that type of installation.
A:AnswerThe previous answer is INCORRECT. According to the SVS Prime Satellite product manual, the threaded insert is 1/4-20 thread. These mounts should work for the SVS speakers.
