Thanks for posting today and welcome to the Bose Community.
This isn't something that is possible as the Soundbar 700 only supports one set of surround speakers.
If you have any other questions please don't hesitate to ask me or the community.

Sound bar 700 is not for professional home theater solution but I see it as improvement for regular TV experience. That is why I installed it in my family room TV but not in media room. I can say it does very good job. It's my personal opinion.
