Hello community!

I am a long time user of Sonos and over the years have purchased different systems in my house. 

I have a living room with an ARC and SUB gen3 that I am planning on adding surrounds and the question relies on whether I get the ERA 100 or 300 based on my room configuration.

My coach is against the wall and in a corner so I can only place surrounds in one spot with no much room to experiment with..

We watch lots of Dolby Atmos movies and my first option was to get the 300´s but I am worried about sticking a 300 in the corner (see picture) due to sound reflections not being redirected properly or boosting low frequencies quite a lot on that spot. (I know true play can correct for this) On the other hand the other surround has plenty of room (acoustics) as the living room extends quite a lot on the other side.

I know if I get the 100´s I won't enjoy atmos on the surrounds and these might be more forgiving as they fire towards the front and not sides but I dont want to regret not having the 300´s if the room can handle it.

Has anyone experienced a similar potential setup like this??

Thanks!
