Dual 4" (100mm) 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 520C centre-channel loudspeaker delivers accurate low-frequency sounds from a pair of 4-inch (100-millimetre) ribbed PolyPlas woofers. The ribs improve strength while reducing distortion. The result is rich, articulate bass.
