Don't worry about looks (assuming that is a possibility for you, I know some people can't get past looks) and just think about how they sound.
That photo certainly has me worrying about the looks!
I don't think it is generally possible to have speakers too big for a room.
We can see that. ;-)
Glad you are happy with massive Tektons.
For me, life is too short for big ugly speakers. There are plenty of speakers out there that sound great but don't give me nightmares.
