Focal Sopra 2 vs Sopra 3?

my room is approx. 18' x 12' (I say approx. because there's a portion of my chimney in there and it's "L" shaped. I was surprised the 3's only went 1HZ lower than the 2's. I would think the 2 with a sub might be money better spent?

tnx...2bz.

Just FYI.....

I spoke with a Tech Support person from Focal and asked which speaker (Sopra 2 or 3) he would suggest for my 18' x 12' Basement room. He said definitely the Sopra 2. The 3's would almost certainly produce bass problems in that size room. I'm very happy since I already own the 2's and LOVE THEM! Now I'm not thinking "What if?" 

Hi atekelidis,

I've been thinking about upgrading  (although I love my Sopra 2's!) to the 3's or the Scala (my room is 17 x 12 with a low ceiling). Was there a substantial difference between the Sopra 3's and the Scala's (appreciate a little description) 
tnx....2bz.
