Many installers will plant a treated 4 x 4 timber in cement in appropriate spots and than deploy either 251's or 281's. The Control 29's have a more robust high frequency compression driver, which makes more sense when having a microphone through the system. The system Paul was alluding to was installed 3 or 4 years ago, as I recall.
Here's an example of a 4x4 post installation. This is for an outdoor WAP, but same setup works for speakers too. It's a 4x4 cedar post prepped by the carpenter. He angles the top so water sheds off and then cuts a slot around the post farther down where copper is bent into the slot and wrapped around the post with some type of sealant for protection against rot at ground level. Near the bottom, the copper is wrapped in bitchathane for more water proofing and the post is set in concrete.
A length of pressure treated 4x4 sunk in some concrete is probably just as effective, but I seem to work for people that go to extremes with the details...
