Best speaker that Proac ever made

I don't mean to sidetrack the thread, but since you guys are all gathered :-) Is a 12x12 room too small for the Response 3? I've never heard them but I've heard the D2, D15, D25 and Studio 140 and loved all of them, and wondering if the Response 3 can be used in a small-ish room with listening distance of around 6 feet.

Thanks Jperry and Zydo, I ended up going with Proac D2 instead and they're perfect in my room. I appreciate the input, every little bit helps.
