I have an hd tv and I want to know about wireless surround sound.?

Question

I want to know much it costs, the different pieces, and any extra cables needed.

Answer 1

Wireless surround sound systems work fine by transmitting audio signals to the individual speakers via multi-radio frequency transmitter.

Wireless speaker systems can be a bit misleading though.
Just because actual speaker wires are not needed, remember these types of speakers require a power source to operate.
(Wireless speakers are referred to as an active system due to the intergrated electronics. Wired speakers are referred to as a passive system.)

Just because you’re not required to run speaker wire to each individual enclosure, it may not be convenient to run AC power to each speaker for its proper location to recreate an accurate sound field.

Bottom line, think about if you want to run smaller speaker wire or AC extension cords.

Answer 2

The current issue of "Home Theater" magazine has a round up of wireless speakers and systems. I have it, but have not had a chance to read it. But it should be in the stores now so run out and get a copy.
