Best speakers for a small room

For actives, either LS60 or a pair of Cabasse pearl. I've heard both in tiny listening rooms  (tinier than your dimensions) and they sound surprisingly good for near-field less than 2 meters, especially LS60. LS60 is more refined, colored and laid back. Pearl is slightly less refined but less colored and more fun, and you can put them on TV console without stands. 

For passives, I may be more partial towards Cabasse because I'm using one now but I believe Riga and Baltic are perfect for small rooms and have extremely high WAF. If not Cabasse, I would get Sonus Faber Electa Amator III, Triangle Magellan Duetto, or Focal Sopra No 1. 

I had the Triangle Comete 40th for a few months. I loved it to bits and I think it's arguably the best bookshelf speakers for $2-2.5K you can buy now and even better than most in $3-4K range. 

I upgraded to Cabasse Riga. It's 3 three times the price but in every aspect superior to the Comete and equally addictive to listen to. 

The other two options under 10K for bookshelves that really warrant serious considerations are AudioVector R1 Arrete and Yamaha NS3000. I listened to both and they are very fun to listen to and are definitely flagship quality. 

I've not heard many floorstanders yet, but I remembered being impressed with Amphion Argon 7LS.
