That back wall is pretty wide, I'd like to hear other people's opinions on mounting them on the back wall instead of the side wall.

Then again you did ask #1 or #2?

I think location #1 looks bad on paper but I think it would work fine once it was set up correctly.

Location #2 would certainly sound fine but I think the speaker location might be a difficult sell to your significant other.

With a room that wide I'd try them on stepladders against the back wall and see how they sound.
