I bi-amp my speakers and am wondering if the gains of the two amps should be matched. I am using a homemade "Honey Badger" for the bass and an Adcom GFA-555II for the treble. The crossover and 6th order alignment filter for the bass have a +-6dB potentiometer.
I do know the "Honey Badger is supposed to be 40dB gain and the Adcom GFA-555II has 27dB gain.

As long as you can adjust the relative levels with the pot to match the acoustical outputs of the bass and treble,
you are good. If the bass is still too loud with the pot at minimum, add an attenuator at the input of the bass amp,
set at around -12dB.

I tri-amp and use all different amps. Just adjust for the efficiency of the drivers and gains of the amps as rayma said.
Although I found some real Sankens for the outputs in my HB and my bass sections are a 4 ohm load.
When I was driving them with twin Proton D1200's I noticed the treble actually pulls more wattage when driven hard, so I installed them the way I did.

So 150 at 40 and 200 at 27, sounds like they would be close when driven by the same signal. I wouldn’t run that much but power to the highs but that’s me.
