Take a look at this, it should show you how to bi-amp. You don't bi-wire if you are bi-amping your speakers!
Sounds like a good opportunity to try them all and learn about the speakers and amplifiers. If you do, please do report back on your outcomes...
That said, I find a single amplifier running each speaker (full-range) to be best *in my system*. I lose coherency with different channels running the two sections of my speakers in a vertical bi-amp setup. I never tried the horizontal bi-amp due to insufficient speaker cable length.
@yogiboy Thanks, that link helps a lot.
@oddiofyl the specs for the Aegir give it 80W at 8 ohm when used as mono. Do you know how that will be different if I vertically bi-amp? Would it be correct to assume 40W for HF and LF for each speaker?
I am leaning towards vertically bi amping as I think I will see more benefit with separating High and low frequencies rather than just throwing more power at the speakers. I typically don't push them too hard and listen at reasonable volumes. Although I could be wrong as I have no real world experience with this and am going solely based off what I've gleaned from various discussions on this forum related to this topic. I am however all ears if you want to explain your position any further..
