My review
Used on an 8 inch sub made with fiberglass. It sounded good

I built a small .35 cu ft box + displacement for an 8" Polk MM840 DVC sub. I stuck with the manufacturer's sealed box recommendations and added this passive radiator. The lows are awesome, the tone is phenomenal, I am shocked by how good it sounds for one small 8" sub on about 300 watts of power.

nice bass, built custom box for it

perfect for diy bluetooth speaker box builds that utilize a dedicated subwoofer
A bit pricey but it definitely gets the job done with a sealed enclosure. I use these for diy bluetooth speaker box builds that have a dedicated subwoofer.

Works great for DIY Small speaker enclosures.
Product works great in an Apache 3800 DIY Speaker. I have this paired with two 6x9's and it woke up the low end and allowed more air space for the 6x9's to scream. Only 4 stars for the fact that this is the same price as a complete subwoofer, when all your purchasing is a lightweight disc. Also, would be nice if Kicker would supply a grill for this as well for the price.
