Kevlar Vs Carbon Fiber Speakers

The passive crossovers will have more to do with how they sound than the materials used to make the cone.

Kevlar vs carbon fiber speakers. While kevlar carbon fiber are both very strong they re only strong when woven as a reinforcement of some sort of plastic the resin. Same applies to the hot debate of kevlar vs polypropylene speakers. Still many of the carbon fiber coned drivers do offer excellent characteristics. Carbon fiber however is mostly used as part of composite materials in a formed or woven state.

However as a chemist and somebody who worked on polymer science and materials i feel there are a few missing points which could help explain some of the characteristic properties of carbon and kevlar fibers. It s lightweight and durable. But we know a majority of you reading this aren t as knowledgeable on the details. Moreover it s tough and flexible thereby attains high output.

Kevlar fiber has a tensile strength comparable with that of carbon fiber a modulus between those of glass and carbon fibers and lower density than both. Carbon fiber and kevlar are some of the most common fiber materials used in making cones. Kevlar aramid is used for high performance composite applications where lightweight high strength and stiffness damage resistance and resistance to fatigue and stress rupture are important. Carbon fiber kevlar many speaker manufacturers claim to use exotic and highly specialize materials in their systems with all kinds of fancy sounding names colors and finishes.

The material used to create a perfect speaker cone would need to be as stiff as steel light as a feather and able to start and stop on a dime. So here is an objective breakdown of each speaker material. It can sometimes be very stiff allowing the monitoring speakers to produce the intended sound. The important thing to take away is that carbon fiber is about twice as stiff as kevlar and about 5 times stiffer than glass.

Unfortunately the perfect driver does not exist in the real world so speaker designers select materials that allow them to get as close the ideal as possible. Kevlar kevlar is a fiber material often used to create body armor for police and military use. Between the sq of kevlar vs. Many speaker vendors have incorporated kevlar into their cones usually woven and formed either alone and coated or as part of a sandwich construction.

All the answers are pretty good. Carbon fiber is mostly used in woofer drivers. The actual figures presented here are for comparison only. Carbon fiber is by far the stiffer of the composite materials.

The details that go into determining what material is right for the speaker isn t different.
