I am a newbie and looking to get my first 5.1 surround in a 12x16 living room with vaulted ceilings and hardwood floors. TV over fireplace. I am looking at Polk 65RT in Wall speakers for surround and left + right speaker. Center speaker may be Klipsch RP-250c REF premiere 5”. Sub is Jamo J10SUBBA 10”. Is the center speaker okay with the Polks, have similar sound profiles? Anyone have the sub and what are your thoughts on the sub? Thank you!
