The speaker is designed to be run either one of 3 ways.
Integrated, as it is now, for one amp.
Second is to be biamped with the original tweeter crossover using one amp for tweeter hooked up between jacks 4 and 2 and the jumper 7-8 in place, The bass amp is connected at 3 and 5 and all the other jumpers are taken out. The bass section will then need to be crossed over with a line level low pass filter before the bass power amp. That consists of a resistor and a small capacitor in parallel or shunt position.
Third, You can also run the speaker with a line level crossover for both bass and tweeter, which is likely to perform best. The tweeter amp is connected at jacks 4 and 8, The bass amp is connected at jacks 3 and 5, all the jumpers are taken out.
The crossover at line level consists of a small series capacitor between the preamp and the tweeter amp for the high pass filter. The low pass filter consists of a resistor and a small capacitor in parallel/shunt position.
You can also use a line level active crossover like the First Watt B4 if you need more gain than the preamp provides.
