Chris and Doc, Thanks for the explanation.
Blu-ray movies have a lot of content below 40hz with even some subsonic content with extreme dynamic range.
I thought only the LFE channel would go below that, not the FR and FL, ie if you don't have a sub they shouldn't be required to play these frequencies. I guess I am not properly understanding the difference between "regular" bass and the LFE channel.
The M80's will sound a lot cleaner and handle more power set to small crossed over to at least 40hz.
The reason I don't have them to small is because I don't have a sub yet so I can't cross them over. Even though I rarely watch BD at very high levels, the few times that I did I thought the M80s were doing an amazing job. The only 2 scenes that I ever heard the "flapping" were in IronMan 1 when he goes to Afghanistan and enters sonic mode and in Peter Jackson and the Olympians at the beginning when Poseidon first steps to the ground. Other than that I never heard anything else wrong.
