Well, with sensitivities that low, you're going to need an amp with a lot of oomph to power either.

Wilson Sophia 3 is easier to drive than Sophia 2 ?
hi, I asked the factory and they replied:
" The sensitivity’s are the same between the Sophia Series 2 and Series 3. The Series 2 was measured at a voltage of 2.83 volts - the Series 3 was measured at a voltage of 2.0 volts. When you bring in the 4 ohm impedance, the 2.83 volts adds 3 dB.
Hence, they are the same."
Sophia 2 89db
Sophia 3 87db.
but I read many things and some say that the 3 is more difficult to drive.
