Clearly a subjective topic. Unlike Rich, I find the Spendor SA1 to be a very good speaker in a small room. Also like the B&W 302, go figure.
There are dozens of discussions about small speakers in small rooms. Do a search.
I have tried many in my 12 X 10 room.
There are many that work well, many don't.
The best for me are Audio Note ANK, they like tubes though. Others in no order
Linn Tukans or Katans
Harbeth HLP 2 or 3
Proac Tablettes
Merlin TSM
Kudos Cardea C10
Joseph Audio
The list goes on...and on
All it takes is time and money :)
