Samsung has a full lineup of Home Theater systems here:
There is no "wireless" home theater system for all of the speakers, but there is an option to avoid the wire that runs to the rear speakers. We use a wireless box in some models that will transmit the rear speakers wirelessly. (Though, you still need to plug in a transmitter for the rear speakers and run speaker wire). It's a step in the right direction for some applications.
If this sounds like something that interests you, look through a couple of models, and I'll be happy to answer your questions regarding units that may interest you.
I'm shopping for a Home Theater System; probably "in a box", preferably plug and play or wireless.
My current receiver isn't working anymore and the thought of wired speakers is more than daunting...
Any suggestions for a compatible Home Theater system?
