Trying to set up new Polk Atmos speakers.

[blackwidowavenger1964]

So I currently have speakers mounted all around my theater room. I currently have 5 Boston Acoustic speakers. They sound and work great. I also have a Polk Audio subwoofer which I really do like. So I just ordered and it arrived, the OMW3 speaker which according to Polk Audio can be angled and used for Atmos. (Not someone with a huge bank account so really not looking to be lashed out for my speakers which were on the cheaper end). I just noticed, it did not come with speaker wire. The last set of speakers I got came with them so I am a bit confused. Which speaker wires should I buy? I plan to do Best Buy's buy online pick up in store. Does the wire really make a difference in sound too? I see Rocketfish for more money but I also see Best Buy's Insiginia in house brand which seems to have good reviews as well and on the cheaper side. My receiver is not that far from where I want to angle the speakers. I have this unused bar area in front of my TV which I will probably set up the speakers to angle at the ceiling for atmos effect. This is one of the brand of wires I was looking at but Best Buy's in house brand gives you 20 ft more of wire for the same price.

I know it's not the ideal place for Atmos but my ceiling isn't properly installed or ready or even capable to handle Atmos in that way so I will be doing the angled. Any suggestions?
