Sure is nice when it all comes together like that did Dave.... that was a monstrous peak ya had there buddy....
Frank take note.... when you cut a bunch of freq's to level things off in your room you will lower the output of your sub, but intern you can increase the gain on the sub output, or output level of the SMS as well to compensate.
Dual subs will help alot in balancing the bass in your room, which usually makes it easier to work with the EQ.
