When the Streambar Pro was announced it listed the virtual surround feature, it then said it was coming to the original large Roku Smart Soundbar in a future upgrade. Nothing was said about the small roku streambar getting it. Maybe the little box can't deliver what the what the larger ones can, and the power. I own two original roku soundbars and one small streambar. I don't use it, surround always gave me headaches.
Thanks. I guess they decided it isn't wide enough.
