Product details

Seas Prestige ER18RNX-8 - H1456-08 7" Reed Paper Cone Woofer

 

The ER18RNX is a 6,5’’ cone driver, developed for use as a long throw high fidelity woofer or woofer/midrange unit. Edge coated reed/paper pulp cone together with perfectly matched moving parts gives a smooth, extended frequency response.

 

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. Heavy copper ring below the T-shaped pole piece will reduce nonlinear and modulation distortion.

 

Extremely stiff and stable injection molded 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.
