I bought a pair of these for the rear speakers in my HT setup. I was a bit wary of the cheaper mounts and they weren't overly expensive but proved to be well made and perfect for my use. Basically a metal construction with mounting screws and dowels, they hold my Polk OWM3 well. The Polk is listed at 4.4 lbs each and the Panavise mounts are rated for a maximum weight of 8 lbs. I personally wouldn't want to go much over 5lbs as I think it might be too big for the ball joint, but if your speakers are 5lbs or less I recommend these mounts.
