This is the Bose Lifestyle 5, there was an earlier system that was quite poor so this is genesis. The series I and II uses the classic redlines which are going up in value when in good condition, this is series II with the popular twin cubes. These have no digital inputs so cannot decode 5.1 . These are now dated and most have failed led displays and or cd mechanisms. The remote is the RC-5. Good clear sound and quite punchy bass, good for smaller rooms giving retro looks.
