Totem Arro in larger room??

Hey guys. After auditioning several different brands, I've narrowed my choice down to Totem. I just seem to like their sound. My question is this, would an Arro with a sub (maybe the Totem Storm) work in room that is 17' x 29' (open living room / kitchen area)? The speakers would be placed on the short wall. Music to be played will acoustical, adult alternative (dave matthews, oar, kings of leon, etc) and some classical / piano.
I really like the Forest, but I'm not wanting to invest the $3000+ grand it would take to purchase these. Wanting to stay under $2000.

Thanks for any input!
