Sure but they use a different technology.
Actually Kal, I see a great use for these for many regular folks - one simple device that puts out "surround" sound and does not require a ton of technical know-how, space or setup but is still better than the TV's speakers. I may demo the Yammy for my parents as they want something very simple for movies (they have a music-only 2ch setup).
Nope. These appear to be only stereo speaker simulation from a single box and accept only stereo input. They do not pretend to create surround sound but to expand/enhance stereo. Thus, they are NOT single-box solutions for a surround system and, frankly, do not seem to have any real usefulness.
