    This is what is cool about the class D's.The PPI PH900.4 exhibits less than .05%THD all the way out to @ 130 watts rms, and does not hit 1% THD until 150 watts rms output.



    A visual of that wide band frequency response showing that LPF at 20khz on out to 100khz...pretty dang flat from 10hz -20khz.



    op..here is some good reads:
    PASMAG | PERFORMANCE AUTO AND SOUND - Precision Power P900.4 Amplifier

    PASMAG | PERFORMANCE AUTO AND SOUND - Soundstream REF4.760
