Funny... I asked a question to management here about this exact same thing just 4 days and got a responce. I asked since my vp150 must be a version 1 with NO set screw in back, I asked what wouldbe the best way to mount this above my tv on the wall. The responce back was to use the mounting bracket as it was designed to be used with the center screw on v2 and v3, but also designed for v1 without the screw by using 4 1/2 inch wood screws in the holes surrounding the center hole. ( see picture attached earlier in this thread ) So, 4 screws holding the bracket on the speaker in a circular design over a 2 or 3 inch area. I think I'll give this a try.... OR.... glue/screw a back wood plate on the back of the speaker secured by 6 or 8 screws, THEN use the bracket and its 4 mounting holes using 1 inch screws (since the back plate Ill put on will be 1/2 thick. The stress will be spread out and managed by 1 inch of mounting material, instead of 1/2 inch. Makes sence?????
