Hi all. I have added a second base 500 module to the Bose 500 sound bar. It is easy,
fantastic, room filling and desirable. So now, I would like to know if it's possible to add a second set of surround speakers? I understand it is a 5.1 system, however, I would like to know if it is possilble to add an additional set of suround speakers as I did with a base module?
