Hi all This might sound weird but should I stick with my 5.2.4 set up or try a single rear it allows it in my marantz 6014 amp and I have a single quality speaker but it would need to be positioned in the ceiling rear to the atmos speakers that are already ceiling mounted I can't do a full 7.2.4 as my sides have no option except in the rear pointing inward position I did try using my rear atmos speakers as sides but didn't like the effect any advice would be appreciated regards steve
