Room size & choosing speakers


I am new to all of this and trying to find best size speakers for a small room. I recently listened to B & W 802D's (with a McIntosh MC452 & C-50) at a local audio store & loved the sound. It is a great deal of money for me, but worth it if I can create that magic at home.

My fear is that I will be listening in a 10' x 12' room and that the speakers will overwhelm the room. I also think of the B & W 803D's (smaller, less money, not quite as full sounding), and still have the same fear.

Right now I am trying to decide between the 803D's & the 805D's with a good subwoofer (possibly Rel 328 or JL audio F112). Any thoughts or help greatly appreciated.

Sonus Faber does not have the level of depth and wide compared to the Magico's. Respons is also not as quick as the Magico's.
I was disappointed with SF Olympica I. My friend and I both commented after one song that they seemed flat, mushy, lacking in depth or musicality. I have B & W PM - 1's at home (at 1/3rd the price) that sounded considerably better. The sound was so disappointing that I later wondered if the dealer had made a mistake with the wiring in setting them up. In terms of my own ear, they were the least interesting of the 13 pairs of speakers I auditioned. They didn't draw me into the music, where as virtually every other pair did. I hope that this is helpful.
It has also to do with the combo. Often they want you to buy the most expensive one. You can easily influence the outcome of any speaker! (when you want to)
