The Liberty home theater system by B&W is a beautiful thing. It's 5.1-channel surround system that you can expand to 7.1 channels with an extra zone. But the best aspect of this gorgeous system is that it's wireless, sending audio signals to all the channels over the air. Don’t ask me what frequency it broadcasts on because the company reps won’t tell me. The one thing they would say is how much it will cost and when it should hit the street. It’s expected to be available in September and cost a mere $15,000.
