Summary: The Lifestyle 48 system comes packed with features and includes a calibration disk that automatically tunes each speaker and subwoofer that ensures the system is optimally tailored to the room. I think some folks forgo reading the manual and end up less than successful in the setup, tone adjustments (treble-bass balance) and the all-important placement of speakers.
Summary: Bose Lifestyle 48 system outperforms all previous Bose Lifestyle and Receiver Acoustimass combos. The Bose Lifestyle 48 system has now made other high end speaker and component manufactors step up the luzuries of the entire home theater system application. You cannot find a better sounding Bose speaker - bass moduel - media center combonation on the market.
