Overkill for small room

@letshearit no worries, thanks for the clarification!

I think they are fantastic speakers. You are right that they would be a better fit for a bigger room. I have the Evoke 20s for a room similar size with 1 sub, and they are awesome. The moment I can afford a pair of used Contours, I will buy them! I heard them many times at a local dealer and I love them.  

Here is a good explanation of damping factor

It is a combination of the amp and speaker and it applies regardless of woofer size. I believe you have the correct general understanding.  I’m no expert on it though. Others here might have better insight.  

Those speakers will be fine in your room. But you will need a beefy amplifier to drive these. They are rated as 86dB and 4 ohms, Ouch!. An amp tat can deliver high currents should drive these comfortably.

@letshearit  I also have a room about that same size with a pair of Sonus Faber floor standers. I’ve found moving them well into the room and about 8’ apart solves wall reflections and some nasty bass nodes. I guess you would call it near field listening. My amp is a 140watt PC tube amp. The carpeted room sounds pretty fantastic. I don’t know the speakers but if you have room to play with positioning then I imagine even a larger speaker would fair well. Anyway…I hope so as I’m considering a size upgrade. Depends on this years taxes…! Good luck…!
