Thanks guys!
Im sure Ill find a way now to see if theres any leaks. Im pretty sure theres not, but its always good to check.

Actually the reason I ask is because I think my sub is sounding a little boomy.
I built a 12inch shiva subwoofer with a 150w amp mounted external to the box. My box volume is 60 liters and is packed with stuffing. According to the design, a box volume of 54 liters would give a Q of .707. I made mine a little bigger to lower the Q, to get a less boomy sound. I was interested to hear that a leak would actually lower the Q (I guess it makes sense though)
Ive tried changing location of the sub without much success. I am now thinking of hooking up a potentiometer to one of the coils to control its stroke.
Does anyone have any suggestions what else to try before I open up my box again?
If my amplifier has a bass boost, would this make it sound boomy?
