When Bi-amping is there change in sensitivity


I am thinking of Bi-amping my speakers with a 80 wpc tube amplifier driving mid & high frequencies and a 500 wpc solid state amp to drive the LF driver. I was wondering if the tube amp will be able to keep up with the same volume levels as the solid state amp. I assume that it would be possible if there were difference in sensitivities for the LF and mid/hi frequencies. Does anyone know if the sensitivities change when bi-amping or if it stays the same because of the crossovers?
thanks

Thanks for your response, Al. The tube amp in question does have level control to try to match the gains in case of bi-amping. You mentioned active crossover, would that be a more preferable approach over the passive bi-amping? In that case I would be able to adjust the gains from the crossover itself. And if I end up doing this, would you suggest removing the crossover from the speakers?

Another question I had was if the transients in the mid-high frequencies require as much headroom as the transients in the bass region. Would a 80wpc amp be able to give enough power to provide clean high volume sound (mid-high only) with a moderately affecient speaker, say 89db sensitivity?
