yep, bass above 130-135 dB is usually pretty badly distorted. Sealed boxes are not as bad, ported boxes trade distortion for higher SPL. The acceptable distortion levels for subs is actually pretty high (around 3%), maybe that's because the human ear is not very sensitive to low frequencies. A good way to lessen the effects is to make sure you have no rattles and as little body panel flexing as possible.
