About the Kicker 47KBRW8 ReFLEX™
Big boom for boxes with low internal volumes
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 8" subwoofer, Kicker's 47KBRW8 8" 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. Kicker recommends using a subwoofer with a recommended box volume of 0.4 cubic feet, such as a Kicker CompRT subwoofer.
Note: This passive radiator will not produce sound by itself. It must be paired with a subwoofer in an enclosure.

Works great! It's advised to place the PR on the same plain as the subwoofer but mine isn't and still works great and is still in phase!!! It's paired with an old Infinity Beta 8" in a custom stacked fab box. It really helped the bass but it's made the box dance better than I can!!!
