Yep, my first thought was the speaker wire from the amp to the driver was bouncing around on top of the port, so I secured it with some electrical tape. I also noticed the negative (black) post on the back of the amp was a little loose. I assume the nut on the inside of the amp case didn't get tightened fully during mfg. bug I didnt' want to crack open that amp at this point. I also secured it down with electrical tape to rule it out.

I've been working with Axiom and tonight will verify that no air is escaping around the driver or amp seal. The slightest bit of dust or mdf chips can create a escape route for air and can cause these vibrations...
