General Features


The JBL 4309's powerful, 6.5-inch woofer takes advantage of core JBL engineering techniques to ensure very high output with low distortion. The long-throw voice coil — in conjunction with the symmetrical field motor design, flux stabilization ring, and copper shorting ring — guarantee maximum output with low distortion. A pure-pulp cone provides a lightweight, rigid diaphragm and helps to eliminate breakup modes, ensuring proper pistonic motion throughout the operating band.
