Ok. I experimented with the crossover and speaker settings and there is a huge improvement in the bass. It's strange though as my front speakers are Axiom M80's which are supposed to have alot of bass. But the bass is increased dramaticaly by setting them to small sending alot more signal to the sub. I also have full sized rears which I had set to large. All my speakers are now set to small at 60 hz. It's still a little cold sounding but not nearly as bad as before. I think one of the reasons why this was a problem is changing settings isn't instantamious. Theres like a two second delay whan making changes. You always have to remember to make a change and wait to hear what happens. If you don't your way off with what you were looking for.
