“Please clarify this answer about using these speakers in countries with 220 voltage. Is there a different cord we buy from Bose, or do we just need a power plug adapter to fit the country plugs. What do you mean by different line cord? =========== answer 1 Hi there. The Companion 20's power supply is dual voltage. It can be used in a different region by replacing the line cord that connects the power supply to the outlet. Thanks for the question. 7 months ago Posted by: BoseAnswers from Framingham, MA”
