Thanks!

I would like some help making a decision on what speakers it add to my home theater. I keep doing more and more research and I seem to just be spiraling around. I have a 14x18 room. I have the 65" 4k tv on on of the 14' walls. I have two chouches, on behind the other. the second one will be going on a 12" platform. I have R-14m as a left and right, and a 25 C for center. I am trying to decide if the R-15M or the R-14S would be better for the rear left right surround. I'll probably get the R-10SW's for the sub woofers. Any advice at what properties I should be looking at to make the bets determination? Thanks.
