B&W has launched their new wireless 5.1 Liberty speaker system that is based on the XT line. The Liberty consists of four different speaker models powered by integrated class-D amplifiers. The most interesting feature of the Liberty though is the dynamic channel selection. Instead of using the typical 2-channels for wireless audio, B&W is utilizing a system that changes frequency on the fly and always chooses the least trafficked frequency band for the best sound quality.
The Liberty system is expected to be available Fall 2008.
