I prefer the C2 over the C1, but neither need a sub when driven with appropriate amplification. The C2 is one of my personal favorites from Dynaudio, but to be quite honest, we sell C1's 10/1 over all other Confidence models.
I own the C1's and I chose to mate with dual subs. In my room I found it easier to blend them in and smooth out the bass. I would say I only use the subs maybe 50% of the time, though.
