VERY COOL. Wonder how hard they were driving them to get those woofers moving. Mine never budge, And are played very loud at times.

They most likely just fed the woofers a low frequency signal below the tuning frequency of the port so the driver unloads and starts behaving badly. It doesn't take much to make them move like that. Just a little psychological marketing trick to make it appeal to the SPL addicts: "Whoa, look at that woofer move...those must crank! Sweet!"
