Pioneer announced four new home theater packages for the Japanese market today, but the only two that interest us -- the HTZ-555DV and HTP-S707 -- are the ones with wireless rear speakers. Both "Smart theater" setups, as they are known, support Dolby Digital, Dolby ProLogic II, and DTS, and both also feature the Multi Channel Acoustic Calibration (MCAC) system for automatic audio adjustment. The only major differences between the two packages seem to be the tower speakers on the S707 (pictured above) and the DVD player that's included with the 555DV (pictured after the break), which can handle MP3, WMA, AAC, MPEG-4, and JPEG files plus USB flash drives, along with the obligatory DVDs. Both models are expected to hit stores in late May, but only the price for the S707, 89,524 pre-tax yen, is known.
