The most common materials used for speaker cones are paper, PP and kevlar. Each of these materials has its own sound characteristics, its own advantages and disadvantages. Let's take a look at some of the characteristics of each material now.
PP cones are a popular choice given their low production costs and inherent manufacturing consistency. PP cones typically have good damping characteristics and are widely popular in high-end loudspeakers, offering good consistency and low distortion, as well as good performance in all areas
While paper cones have a brighter, more "realistic" sound, they cost more to manufacturers. While their sound quality is usually ideal, paper materials readily absorb atmospheric moisture and change their composition over time, altering the tonal characteristics of paper cones. Paper cones also come in a myriad of variations: some manufacturers treat the paper to obtain a rounder sound. Others use untreated paper, which produces a brighter, broader sound. Paper cones, also available as non pressed cones and press cones,paper cone have a natural sound, are inexpensive, made of hard, lighter materials, and are highly sensitive. The best HiFi systems are equipped with paper cones because they have a very even sound and good reproduction.
Kevlar cones, with a wider frequency response and lower distortion, is the first choice of those who love strong bass, the disadvantage is the high cost, complex production process, sensitivity is not very good light music effect.
