How to equalize a bi-amplification setup?

Greetings!

Any one experienced in bi-amplification setups with different amplifiers, where output must be equalized?

In my bi-amp setup I use one pre-amplifier connected two different amplifiers, via balanced and unbalanced connection, feeding a pair of 2-ways loudspeakers (Pass Aleph P, Pass Aleph 3 on tweeter and Pass Aleph 0s on woofer).

Problem is the Aleph 0s results in a final higher sound volume (at least +3dB). Theorically I think this should not happen as manual gain of both amplifiers indicate a +20dB gain, altough the Aleph 0s outputs much more current.

How can I "calm down" the bass amp without comprimising the sound quality and without opening the loudspeaker to introduce one attenuation circuit?

An easier solution:

Whatever interconnects you are using, contact the company and they can make you a balanced Y splitter so that the output of the amps will be the same. Feeding both amps balanced will probably also give you better sound.

Sony,

Unfortunately, no.
