12" Polypropylene Cone With Rubber Surround

12" polypropylene cone with rubber surround

Description

12" polypropylene cones with rubber surround are easy to work with and work quite well. Because they are fairly rigid and very well damped, plastic woofers have controlled attenuation, which results in a smoother high-end attenuation. Some plastic woofers may not sound as dynamic as their rigid cones, but with proper design, a well-damped plastic woofer can produce excellent midrange frequencies.

12" polypropylene cones with rubber surround are popular in both high-end and car audio speakers because they don't absorb moisture and have low distortion. Preventing moisture absorption is more important than you might think, because cone quality, quality factor, resonant frequency and cabinet tuning (in terms of ventilation design) are all affected by humidity. Conventional cones are usually manufactured by thermoforming, in which case the cone is heated until soft and then molded (usually by vacuum pressure).
