Unfortunately, the 3134 crossover in the 4430 monitor does not appear to be "simply bi-wire/bi-ampable". You can select between single input to internal crossover networks, or this strange input that requires a "1khz crossover" in combination with portions of the internal crossover.
To biamp-these you will need whatever that "1khz external crossover" is, be it active or passive. I would ask around about these on the audioheritage.com website - search for 4430 or 3134. Sorry, but it's not a typical "remove the jumpers and bi-amp" situation and results in far more complexity than just gain matching.
Here are some links to get you started...
