Yeh, there seems to be some pretty big nulls. What is your crossover set at? If 60hz, perhaps the speakers are out of phase which is what is causing that null. REW made me realize that my sub distance in my AVR was just wrong, which was causing a huge null around 80-120hz.
I have recently been playing with REW myself and below is what the response looks like at the listening position. The purple line is with Audyssey Flat turned on and the Teal line is with Audyssey off. It does a pretty darn good job imo, but I did have significantly modify the sub distance that it had choosen as it just wasn't working well as you will see below.
The sub is a single F12, set to 14hz, high damping and with the Rumble filter On. I also have PEQ on with a medium bandwidth 3db boost at 80hz (except for the green line).
Purple: Audyssey Flat / 80hz Crossover / PEQ On / 10.7ft in AVR.
Green: Audyssey Flat / 80hz Crossover / PEQ Off / 5.7ft in AVR (default set by Audyssey)
Teal: Audyssey Off / 80hz Crossover / PEQ On / 10.7ft in AVR
