Hi I was wondering if I could do this setup I already have a jbl 5.1 soundbar I plan on getting another exact same.model my question is if I was to hook both of them to optical cables would the sound on the subwoofers come out at the same.time
You want to use two soundbars on one system? Or adding another sub to yours? There may be a delay with them used this way, especially if the system was not setup for use with dual subs. Does not sound like something you will get any benefit from doing.
