Detonator: How to differ power from size

I'm using Detonator framework to create explosions in my game. There is a little problem - the explosion power is not enough to affect my heavy game objects.

When I increase the size of explosion the power gets good, but the explosion visual size is also increased and I want the visual to stay the same. How can this be done through Detonator?

Go into the DetonatorForce component and change the force value in there.
