I owned 30.1's and now own 40.2 anniversaries.
My answer is, it depends on how serious you are about music listening. For me, sitting down and listening is the highlight of my day. I listen actively and lose myself in the music. If I were buying speakers for a common living area where I was unable to listen this way, I would probably choose the 30 series as they are smaller and still sound amazing.
For me the 30.1's were fantastic sounding speakers, but left me wanting more bass. My room is smaller than yours (12x14) so you definitely don't need to be afraid of the 40.2's. They will sound great in your room with proper set-up.
I ran a sub with my 30.1's and really liked the sound, but eventually I grew out of them and purchased some 40.1's. The difference was not subtle. I loved them so much and had no intention of upgrading until an opportunity to buy the 40.2A speakers at a great price came my way last year. I am so happy I made this move. I do not know if the new XD model is better than the anniversary version but I am not even curious about that. The 40.2 line is the pinnacle of sound for me.
I don't regret the journey I took to get here. In fact, it was the right thing to move through the line-up, as it has helped me understand the difference between these models.
That said, if you have the means to get the 40.2's I do not think you will be disappointed.
