The amplifier is Linar A105. Here is the manual.
With the amps fully balanced inputs, you can expect the impedance to be the 53k between the phases, so your assumption that you need the crossover spec'd for half of that is probably correct. But since they are a little vague on how the impedance is specified I'm not 100% certain.
Refer to their website, FMOD 70Hz high pass filter should be 140hz if the input impedance is smaller or equal to 10k.
So I assume the actual filter for 70Hz high pass should be around 80hz range I guess with the input impedance of amp at 53.3k.
