Kicker 47KBRW12 - 12" passive radiator - big bass without a ported enclosure

Big boom for boxes with low internal volumes

Ports require larger enclosures to be effective and can sometimes produce unwanted noise. When paired with a compatible 12" subwoofer, Kicker's 47KBRW12 12" passive radiator lets you get the punch of a ported box in a small sealed enclosure that can fit in more places in your vehicle.
