Gonna go against the grain here. I had this EXACT same question posed to my Focal dealer Simon no more than a month ago. My room is similar in size, 17x12. And he's adamant about me going for the Solo's. So much so that he practically wont let me buy the Twins and says if I want to upgrade to the Twins within the first 12 months he'll take back my Solos. The reason he said is because of the distance of my sweet spot. Essentially its not big enough to evenly hit my ears. And I thought my distance was actually pretty big. But I guess just not big enough for the Twins. He's very confident that the Solos would give me better translation. But I was just like you, hoping someone would say the Twins are well worth the extra money. Because they look so damn sexy. Usually you'd be happy if someone said "save the money, get the other ones and they'll actually work better for you".
