Review on Monoprice Profile Capacity Speaker Brackets Home Audio by Michelle Hermann

They were pretty easy to install with just 2 screws in the wall. They are very easy to move and have a very good freedom of movement. I have Yamaha speakers and it seems they have a different bracket size. I bought two different speaker mounts (one for the center speaker and one for the back) and had to rebuild both. My Yamaha speakers are attached with a 1/4 mounting screw. The supplied screw for attachment was a bit smaller, I would have used a #10 attachment screw although I haven't checked the size. Very good value for money and the upgrade didn't take long. All I had to do was drill a 1/4" hole and buy a 1/2" mounting screw to match my speaker. But a little extra work.
