If the HP woofer could play up into the mid-range, it would add up to a more sensitive speaker. I do find there's some music and movies recorded at a lower level and I have to turn my Onk up to -5 to -10 with the M5. With the M80v2, I never had to go above -10. I may now be running out of headroom on the Onk. I'd never go back to the M80v2 though.
