Dave,
Thanks for your opinion.  My guess is also the F8's would be a better match in that room. Any one else with experience in a small room?
I have the Nenuphar 10" in a 15’ x 13’ room. Drivers 60" from the front wall and 7’ apart center to center. Listening position 7’ triangle so also in a near field configuration. I’ve tried them in every position I could think of and always come back to this. Toe-in is important. I started with them straight on then toed them in in tiny increments looking for a balance of sound stage and center image.
I’ve noted that in the last year or so Peter B. from AV Showrooms and others have placed them on the front wall and prefer that position in those rooms. It doesn’t work at all in my room. The sound stage collapses in depth, imaging disappears. The bass isn’t all that much if any better. These speakers have magical properties that will manifest for you if you find the right formula for them in your space. If the rest of your system and placement are right they will create sonic places, architectures, landscapes...places for you to go. When Srajan said they are a benign psychotropic drug, maybe he was having a similar experience.
11' x 12' = 132 sq ft = 12.3 sq meters

At the Cube Audio website we find these recommendations:
Nenuphar Basis -- 25-100 sq m
Nenuphar 10" -- 20-40 sq m
Nenuphar Monitor 10" -- 12-25 sq m <====
Nenuphar Mini Basis 8" -- 20-60 sq m
Nenuphar Mini 8" -- 12-25 sq m <====
Nenuphar Mini Monitor 8" -- 12-20 sq m <====
Magus 8" -- 15-30 sq m
Bliss C 8" -- 15-30 sq m

I know that John from Refined Audio has said he slightly prefers the 8" over the 10".

Another avenue to consider is using the 10" with room correction software.  I have 10" Nenuphars in a relatively small room 13 x 15 x 10 and think they work great, but have noticed that some mid to lower bass notes get muddled (I have no acoustic treatments other shelves of records).  I am going to borrow a Dspeaker anti-mode x4 to see if it corrects this.  Won't happen till late July, but I'll report back.
