2 watts o tube will push the Visatons along okay, as long as you high pass the driver @ 100Hz to relieve the amp's output transformers of bass duty. However, now, there is zero information below 100Hz, hence, no bass, which means you now have to concern yourself with dipole bass implementation and active crossovers, real-time analysis, active EQ, and high current solid state amplification. Beyond that the B200 wants some juice, no doubt. These are not shrinking violets, and can easily sink 100 watts or more...
OR, get Charlize and have your way with her.....

so how powerfull is the Charlize?
is there anyway of adding seperate bass drivers onto the OB without having to use a sub amp?
because with my sub, i can never seem to get the right output properly...

I'd call it ~10w at reasonable distortion levels. However, most of the time, you'll never really be using more than 2-3w, as Dan points out: the rest is just headroom, for dynamic swings. http://www.diyparadise.com/charlize.html
Also, though only THD is published on the link, most of these T-amp variations tend toward the fairly innocuous 2nd harmonic distortion rather than the more damaging 3rd harmonic, so a bit of extra grunt is there, should you need it.
Re your other question, yes, but low power amps are probably out unless you go with active crossovers, and even then, I suspect they'd struggle.

A B200-like driver with more sensitivity and lower Qts (0.34 according test report) would the Ciare HX201. I have them running down to 60Hz in TQWTs. For my taste they would need treble reduction, llike Visaton do for the B200. I am using an omnidirectional setup instead.
A cheap solution would be the Ciare CH250. Hobby Hifi have reached a fairly good linearization with two (or three) notch filters.
