Poorly designed mounts
Crutchfield Customer Review (What's this?)
Installed 3 pairs of these to use with my ProCinema 1000 setup. One for each ProMonitor 1000, and 2 for the ProCenter 1000. Even though they are advertised to hold up to 10lbs, they barely do. The plastic ball that the mount clamps onto is too hard and smooth, so the teeth from the clamps do not hold the weight. The speakers continually move down unless you tighten the clamp bolt...really tight...almost to the point of stripping it out. It's an allen/hex bolt and the supplied wrench is super difficult to use to tighten the clamp once it's installed. I ended up using a hex socket with a socket wrench to tighten it. That was the only way to get it tight enough to not drop or move downward.
Pros: They look clean once installed. The white looks great with white speakers.
Cons: Ball joint and clamp is poorly designed.
