Hello,
+1 for the extra subwoofers. If you are not going to go that route I would go with one of the KEF blade 2s. They have side firing woofers that creat a ton of bass. If you don’t believe me go listen to a pair in a room half the size. These things need breathing room and you have it. Also, with such a big room you want the music to sound good outside of the perfect listening chair. These do it in spades. I love the KEF Reference 5s. You would be better off with the blades. KEF has a subwoofer, The KC62 that plays down to 11hz in a one foot square box. It’s like having two of these awesome subwoofers in each speaker. I don’t own KEF Blades but I have heard them at a brick and mortar store close to me. https://holmaudio.com/This store lets you try stuff out in your home on your equipment for free. No buyers remorse. I hope this helped you out.
