    The left channel has suspicious behavior, might be defective somehow. Then again, +25 dB to the bass doesn't sound like a proper design either.

    Was the impedance plot taken from the left driver?

      I usually measure the impedance with both channels and upload it with only right channel. If there are significant differences between each other, I'll stipulate the both channels.

      For example,

    The distortion figures are confusing? What is reaching 2% in the 1-2kHz range? If it is THD, then it will sound terrible.
