Passive Horizontal Bi-Amping question

[Gibsonian]

The gain of 400s, 700s (with pots maxed), Model ONEs (also with pots maxed or bypassed) is IDENTICAL. The only difference is the max power each can produce before clipping

Isn’t the input to achieve full power the same on both the 400 and 700?

No it is not, 1V in on a 400 may hit the power supply clipping limit while the 700 still has room to move and needs 1.25V to hit clipping due to a higher voltage power supply in the 700. What is true is that up to the onset of clipping, the same input level into the 400 and 700 will produce the same power output from each amp

Thanks for straightening me out Joe. This is quite convenient for the passive bi amper

High side Perry, there is little energy in the HF when compared to the lows...

Yes, not close. 400 will be coasting in the top spot. Where do those speakers cross Perry?

I'm thinking those may sound very close to my ESS Rock Monitors which are nearly holographic with some source material. They love the WOPL!

Crossover Frequency
400 & 2,200 Hz

So the cross will be at 400 for biamping. The crossover in front of the mids and tweets will help consume some power but still the bass amp will be doing most of work. Be interesting to see if this improves the sound for you.
