My audiobahn alum10q makes a really weird noise when it hits a low note. The noise can be described as a low pitch whistle. I brought it to different places and ran tests on it but everyone says that its ok besides making that noise. Whats up with that?

Please Help Me Out!!!!!!!!!!

make sure there is a good seal around the part where you mount the woofer and do you have a box with round ports? If your box is ported your problem could be port noise

Yep, sounds like a leaking enclosure to me too.  Or it could be bad adhesive on the surround (especially where the surround is glued to the cone.)
