Unfortunately, you cannot pair any stand-alone CITATION speakers with your CITATION BAR in order to watch TV. It is possible, however, to place your CITATION BAR in a group together with other CITATION speakers (using the Google Home app) and then simultaneously cast audio to all speakers that have been added to this group. All speakers that have Google casting technology can be added to a Google Home group.
The CITATION BAR/MultiBeam 700 can only be expanded with CITATION SURROUND speakers, CITATION TOWERS and/or the CITATION SUB or SUB S.
