Hi. I have a Klipsch RSB-11 Soundbar with subwoofer that I love but I really want to add rear speakers if possible. My living room isn't huge so I don't need anything to bring the house down.
I have my apple TV, blu ray player and PS4 plugged into the soundbar via HDMI, then soundbar connected to TV via single HDMI (ARC).
I want to know if it's possible to add rear surround via digital optical out from TV into an amplifier, then connect the speakers to the amplifier via speaker wire.
Here are the products I want to use.
