JSE Model 2 and Model 4 Woofers

Hello music lovers. Re-surrounding your old woofers is not recommended as new rubber surrounds will reduce efficiency and new foam surrounds will, again, deteriorate over time. Also poly cones "flex" and are not as rigid as the new paper/CF types.

With regard to your old 10" and 12" Inf. Slope woofers they should be replaced with new and NOT rebuilt. Yes, it's about $300 more to replace them, but the new replacements have larger voice coils/magnets, greater acceleration, higher Mms, stiffer cones and are a much better match for the Phase Shift Bass Loading mechanism. This more optimum Vas/QTS ratio will provide better - deeper and more dynamic bass

Hope this helps,
