For a bi-active system, is a Tundra best used for one speaker, or best used for the same driver in both speakers?

I tested this long ago with various amps and believe that the results are applicable to all power amplifiers, including Tundra (which wasn't released at the time).

Most musical was to let each amp drive the same speaker driver in both speakers. E.g. left treble and right treble.

Thanks Fredrik.

I'll leave the rats' nest be for now then :)
