Meadowlark Ospreys X-over frequencies for bi-amp

I am considering bi-amping with an electronic crossover after my preamp. I don't want to mess with the built in speaker crossovers - I not sure how to do this. I want to use a tube amp for mid/high and a solid state amp for the woofers. I am not sure what the crossover frequencies are for meadowlark ospreys. Can anyone advise?

Thanks Cliff
