Bi-amping Rules

I wasn't sure if this question belongs in the amp or the speaker section but I figured I'll post it here. Those of you who have bi-amped your speakers, what's the general rule for deciding which amplifiers are better for low frequency vs. the high frequency drivers. I recognize an accurate answer will depend on the particular speakers and amp combinations but I'm looking for general rules of thumb from personal experiences and not application specific recommendations. For the sake of the argument, let's assume the amps are different but the gains on both amps can be adjusted if that matters. Thanks.

I think even passive bi-amp or tri-amp can achieve great results no?tubes or low power class a for the horns on mids and highs for example, and a high damping factor high power class d for the woofer driver...

Any thoughts on this?

Thanks.

👍 Yes vertical bi-amping is the way if the amps are identical.

Or horizontal bi-amp a good class-A or A/B or tube on the mids and highs and a class-d on the bass.

I currently have a Hafler DH200 feeding my Infinity 6 Kappas With an infinity BU-1 subwoofer. I am considering adding a 2nd BU-1. This distributes 50 wpc with each sub and 100 wpc into the 6 Kappas crossing over @ 150 Hz.
