We custom weighted the KBRWs to exacting specifications, so you get the perfect tune. All it needs is the right active sub in the recommended airspace for some serious custom bump!For rad results, use an 8-inch CompRT or CompVT subwoofer in 0.4 cubic feet of internal air space.

Review: My review - Used on an 8 inch sub made with fiberglass. It sounded good
Review: boomin - 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.
