Default batteries in crossover, like JBL

JBL is using 9v batteries in their Everest system. Can someone explain how to connect batteries to a crossover?
I don't expect any miracles from adding a battery, but still would like to try it.

What you do is this. You replace the existing capacitor with 2 capacitors that are double the originals value in series. That gives you the same value. At the node where the caps join you put a 2-3meg resistor. You take the other end of the resistor and attach it to the +9V of the battery the battery negative goes to ground.

You don't get miracles you get better low level resolution.
