calculating nulls

72.71.61.27

Hi everyone. Quick question , how exactly do you calculate a null at your listening position. Lets say you had speakers 10 feet away and had a null at 50hz , is it half the wave length from the reflection point ( 11.3 feet ) or is it half the wave length from the direct sound to the reflection point and then to the listening position. The only reason i ask is because my friend is starting to treat his room and he has a nasty 9db suck out at 50hz. Thanks again.
