This is KICKER's highest grade speaker, which has remained unchanged for over 10 years since its release. KICKER has a strong image of a woofer, but the front speakers actually reproduce crisp, powerful sound and fine details. It has been used in many demo cars and has a track record of winning many battles over sound quality. It is especially suitable for American music and dance music. Basically it is used as a separate unit, but it is also equipped with a mount that can be used coaxially.
