I really like Sonos Faber speakers. My only reservation in a room that big is that they are on the small side especially given the amount of power you have to drive them. Adding subwoofers would help if you are using them with a two way crossover. The recommended power for those speakers is 50-300 Watts
You might want to consider listening to speakers that are more efficient upwards of 96 dB/watt/meter. I think Klipsch Cornwall IVs would fill that room nicely, you would have less trouble with room interaction because dispersion is limited and 42 watts will drive them to painful levels. But, whatever you are thinking of should be carefully auditioned with your amp I might add. The interface between an amp and speakers is I think much more important than it is given credit. The character of the sound can change rather dramatically due to impedance changes depending on the design of the amp. A good part of the reason you hear conflicting opinions of loudspeakers is because they were being driven by different amps. Any good dealer will allow you to plug up your amp. Always listen to a speaker with the amp you are going to use, always. The program source makes relatively little difference.
Good Luck and enjoy your new room!
