    Hi Thomas,

    Long ramps in the filtered loudspeaker’s step response are usually from the LF rolloff. (Linearising the phase at very low frequencies requires a very long FIR filter.) Maybe post some screenshots of the step response and the filtered speaker’s mag/phase response.

    Best regards,
