I was just thinking about this and my particular situation really lends itself only to sound situated “around” the media screen. 2 or 2.1 would be the logical choice, but what about 3.1? LCR.Sub, no rears. I suppose I could go with 2.1 setup and “sum/band limit” for a center, or would some such thing not be worth it?
Or maybe go with a 5.1 and put small swivel speakers on top of the mains in order to bounce off the walls/ceiling to help achieve the rear surround effect.
Just thinking OOTB.
**Edit
I was looking around and no one makes a 3.1, not even in the weird and wonderful place of AliExpress. That is, unless I just don’t have the right search term. 😁
