This is the Bose Lifestyle 8. The LifeStyle 8 uses the single cubes and the Acoustimass 8 bass module. It uses the RC-9 remote and LifeStyle 5 head unit. This is one of the basic 5.1 systems which has been around 20 years now. Same problems as the Lifestyle 5 bass units are becoming rare as they fail and are costly a to repair.
