Dual 6-1/2" (165mm) ribbed PolyPlas woofer cones
Powerful bass affects more than just your ears. It resonates through your entire body, creating a soundscape that you can feel as well as hear. The JBL Studio 580 floorstanding loudspeaker delivers accurate low-frequency sounds from a pair of 6-1/2-inch (165-millimeter) ribbed PolyPlas woofers. The ribs improve strength while reducing distortion. The result is rich, powerful, articulate bass.
