Your room looks very reflective. I bet there's a lot of echo when you have people over. That might be the annoying sound you're describing as bright. Not sure how well those speakers handle loud though, they look pretty flat unless they're actually in-walls and not on-walls? It could be you're just driving them to crazy levels of distortion. I couldn't find any real information on the speakers.

I'd pick the second graph too.
