Your two satellite speakers' description: "Each Dolby Atmos-enabled wireless rear speaker features a forward facing full-range driver and a upward firing full-range driver powered by a built-in 35 watt amplifier." I assume the upfiring has something to do with its Atmos feature, so you'd need to keep them oriented so the upward firing driver works properly. The full range driver facing forward wouldn't matter as to orientation otherwise....
Well I should have looked up that system first. What a totally miss begotten mess up of a contraption. My, my, things really are on the slide.
I have heard quite a few sound bars now as they seem to be populating suberbia faster then rabbits! They are all only marginally better than TV speakers, and in many aspects worse. The modus operandi seems to be small over driven tinny speakers covered up with a ghastly boomy sub crossed too high in a vain attempt at subterfuge.
It seems that particular item has a lot of connection/reliability issues even when paired with Samsung TVs.
My advice to OP. Do NOT open the box. Return immediately.
This is a fad that needs to die, but probably won't.
I advise a pair of good small bookshelves and a small little integrated amp with an optical connection to the TV. That would get you way further ahead.
