The best speaker for a small room...at any price point.

Wilson Duet is my easy first choice 

Ryan s610's.  Heard them at a show - amazing.

I have a room about the same size as you do and the Legacy Audio Studio HD's work GREAT....I actually have compared the Legacy to KEF and the Paradigm bookshelf speakers and found the Legacy performed much better. The Legacy are some what heavier (about 32LBS ea) then most other bookshelf speakers that I have looked at. Frequency range is listed at 41-30k, with 91 db. This is a 4 Ohm speaker which can be order in multiple high grade finishes and it won't " break the bank " while doing so.   

If a pair ever becomes available, a pair of Sonus Faber Extrema's, with the oval sub in the rear, on the matching stands. Magical, with the proper amplification. And this, from a horn aficionado. Enjoy ! MrD.

@daveyf Unfortunately the Stenheim monitors were on Bryston gear which wasn't a very good combo for my taste- not much bass either, but I could be jaded by the Five demo I had prior. The line has very nice tonality and dynamics.
