Sony has announced their brand new HT-IS100 Bravia Theater Micro System, a 5.1 channel surround system with speakers roughly the size of a golf ball.
The 5.1 channel system, with 450 watts (RMS) of power, includes a subwoofer with integrated 32-bit S-Master® digital amplifier for superb audio performance.
Featuring Sony’s S-AIR™ technology, you can add wireless multi-room listening throughout the home using Sony S-AIR Air Station speakers, which are sold separately. Television audio and music can be transmitted from the main system to multiple rooms throughout the home by connecting the Air Station into a power outlet. An optional speaker kit (WAHT-SA10 sold separately) delivers audio wirelessly to rear speakers, eliminating the need to run speaker wire from the front to the back of the room.
