L16RNX is a 5 Inch High Fidelity woofer with an injection moulded metal chassis, intended for bass reflex and transmission line designs. Stiff, yet light aluminum cone and low loss rubber surround show no sign of the familiar 500-1500 Hz cone edge resonance and distortion assosiated with soft cones. A bumped back plate in the magnet system, together with the very long and light weight copper clad aluminum voice coil, allow extreme coil excursion with low distortion. A heavy copper ring below the T-shaped pole piece reduces non linear and modulation distortion. Extremely stiff and stable injection moulded metal basket, keeps the critical components in perfect alignment. Large windows in the basket both above and below the spider reduce sound reflection, air flow noise and cavity resonance to a minimum. This driver use Seas SpiderRingﾮ technology.
