Sony Japan is rolling out a new home theater-in-a-box system with cube-shaped speakers. As tiny as golf balls, each satellite measures just 1.7 inches on each side and providesno less than 45W, in addition to a 200W subwoofer. The HT-IS100 supports Dolby Digital/Dolby Pro Logic II/DTS and includes 3x HDMI ports, AM/FM tuner, S-Master audio system as well as the Sony's Digital Cinema Auto Calibration (DCAC).

The system goes on sale in Japan on June 25th for 90,000 yen ($890), but no word yet on availability nor pricing for U.S. and European markets.
