"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"

As it was noted above by sdurani, there are very few speakers that can handle the bass as well as a good dedicated subwoofer. You may also find that setting the crossover higher, even as high as "gasp" 120 hz, may improve the response. It is worthwhile to play with different settings. There are a lot of variables in a normal environment setup, we do not live in an anachoic chamber.
I have a 1050 upgraded from a JVC, and I found that the greatest difference, "improvement", came when I changed my speakers; from a varily expensive set to some wonderful diys. I think speakers are the most important part of a system, yes even though a system is made of various intergal parts.
