Are I looking at the wrong bar? It doesn't appear to do surround sound.
Help! Purchased a Sony Ht-NT5 sound bar and paired it with a couple of sony SRS-ZR5 bluetooth speakers. The volume on the rear speakers, even when turned up to 10, is pathetically low; have to put my ear up to the speaker to hear it. This problems seems to be common; must have something to do with channeling through a DirectTV box. Does anybody know if other manufacturer's bluetooth surround sound speakers are compatible with the HT-NT5? Sonos perhaps?
