I'm a bit confused, the point of "side" and "rear" surrounds (not front as you say) is to not be directional, that is the point. They are supposed to envelope or wrap you in the experience, not be diretional.
When you say "forward" surrounds, I hope your talking about the "side" surrounds which should be to the sides of the listeners?
The surrounds are for movie affects and background sounds during movies, unless your talking about cranking up music on them, which they are able to handle power.
My guess is you have something calibrated wrong, or placement is wrong. They should be set to "small" after you run your setup, and probably end up with a crossover around 90hz or higher.
