I am building a hopefully awsome sub this next two weeks and was thinking about how you test a sub so that you can brag about how low it goes. Do you have to have a CD that lets you know?? for instance does it say"This is a 30Hz sine wave.....BBBBBBvvvvvvvWWWWWvbvbbbbwwwww"? I just am not sure how you guys have figured out how low your subs you have built or bought go. Thanks.
......and oh yeah if bizill is reading this, I did not try to piss you off in the post about fixing your rattley ass window.
