Frequency Response
40 - 47000 Hz

    This review is about the colour: Black

    Very high-quality speaker construction, and it also surpasses the amplifiers. But, really, what left me speechless is the sound it produces!!!! It is literally crystal clear no matter how loud I turn it up.
    And if we want the ultimate experience, we combine it with the SubW KC62!!!
    GOODBYE!
