From Vizio's site (JV50PHDTV10A):
Digital 5.1 Surround Sound - The new JV50P "Jive" 50" Plasma display also includes 2-front channel, 1-center channel as well as 2-rear channel plus a free-standing subwoofer. The rear speakers and subwoofer connect wirelessly to the "Jive" eliminating the wire clutter that is inherent with other surround sound systems.
The problem is that this system looks like it's discontinued. It's no longer listed on Vizio's home page. If you're looking for more info on the Jive system, do a search for 'Jive' in the Plasma forum.
