Stevefish, I agree with SteveCallas that you are increasing the risk of bottoming on demanding LF material. If you are the kind of chap who never goes near his sub once he gets it set, match your filter and enclosure tune settings.
If, however, you are like me, changing your sub(s) settings depending on what you are playing, at least for non-1812 Overture music you have found the best EQ in your room -- use it. Just remember to flip the switch before WOTW etc.
