90% of time, playing under tuning frequency of box, with enough power being sent to the sub.

Caused by basically the box having no more damping on the woofer below the port frequency.

almost having no dampening, means almost no physical control of woofer travel.

no control of cone means bottoming out, which means its reaching past its mechanical limits.

apparently you do

Not enough restriction on cone motion for the given input power to the speaker. This may be caused by too large of a box, too much input power from the amp, the sub/enclosure combo unloading from the signal deviating too far below tuning in the case of vented setups, or (most often) a combination of those 3 things.

basically all of the above.. playing under tuning.. its like taking a deep breath blowing it all out and then trying to blow out more..

or if the box isn't properly sealed up and is "leaky." that's the only time I experienced a sub bottom out, when the box was leaking air at a major joint
