These speakers remind me of either a piece of macaroni or a donut, depending on how it is configured. Strange at first, but after taking a closer look at how if can sit on a shelf, mount to a wall or hang from a ceiling I became quickly impressed.
On their own, the 90 degree curved speakers can mount nicely in a room corner for your home theater surround setup. In a group of four, you can hang these from the ceiling pendant style for some general overhead audio.
Available in both indoor and outdoor versions, you will have to save up a bit for these speakers though, they run $249 each.
