That still doesn't explain the sensitivity. The active must be more sensitive even if only by 1 dB.
max power is dictated by the first component to go ... and the drivers are the best suspects in this case ...

There are trade offs with everything ... giving up max power on the driver might have gotten an improvement elsewhere that Bryston deemed more important ... what and why needs to be answered by the designer. In any case I'm still not sure where sensitivity comes in ... unless we are not talking about the same spec.
