That's a huge jump coming from the SF Luitos. My room is approx 26 X 12 with the speakers on the long wall and for me the C2's were too much. What I mean it was a huge wall of sound. In the sweet spot I heard no more bass but everywhere else I did. After 6 days of listening I put my original C1's back and much preferred the sound in the sweet spot. Maybe I could get used to the sound but decided to keep the C1's. Again I demoed the originals not the MKII's and all original confidence series sounded better as you turned them way up. I highly recommend an in home demo if possible because the C4's are a huge chunk of change.
