Thank you for your answer. Distortion is, in fact, higher with the same pressule level when power is lower.
About the 10Hz issue... Yesterday I obtained the spectrum of what I thought it was a 'boomy' modern disco CD. It has, in fact, low frequencies, but these compenents are below 30dB than the main boom-boom frequency around 40Hz.
This was a great surprise for me.
