You need to match the voltage drives and understand exactly what needs to be done to bi-amp them. They use an 18dB electrical on the Woofer and a 6dB electrical on the horn 2435Be. Look at the schematics and voltage drives posted in the referenced links. Going generic will never get it right. If you don't understand how to do the conversion to match the voltage drives best to leave them be in passive mode.
When you switch to bi-amp mode you shunt/short out the 12uF capacitor. There are no other series capacitors so there is no DC protection for the 2435Be. This can be very risky. Normally when you bi-amp or go active with compression drivers you put a large value series capacitor to keep any DC out of the driver so it does not get damaged if there is an issue with the amp.
The 435Be may not be available if you need replacement. At the very least you should seriously consider adding a high value series capacitor just in case.
