All the answers are pretty good.
Kevlar vs carbon fiber speakers.
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 however is mostly used as part of composite materials in a formed or woven state.
Kevlar kevlar is a fiber material often used to create body armor for police and military use.
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.
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.
It s lightweight and durable.
Between the sq of kevlar vs.
Aurum cantus uses a proprietary combination of two of the best materials available.
While kevlar carbon fiber are both very strong they re only strong when woven as a reinforcement of some sort of plastic the resin.
Carbon fiber and kevlar are some of the most common fiber materials used in making cones.
Carbon fiber is by far the stiffer of the composite materials.
Same applies to the hot debate of kevlar vs polypropylene speakers.
There are many types of kevlar glass and carbon fiber and they all differ.
But we know a majority of you reading this aren t as knowledgeable on the details.
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.
It can sometimes be very stiff allowing the monitoring speakers to produce the intended sound.
So here is an objective breakdown of each speaker material.
The important thing to take away is that carbon fiber is about twice as stiff as kevlar and about 5 times stiffer than glass.
Still many of the carbon fiber coned drivers do offer excellent characteristics.
The actual figures presented here are for comparison only.
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.
Many speaker vendors have incorporated kevlar into their cones usually woven and formed either alone and coated or as part of a sandwich construction.
Carbon fiber is mostly used in woofer drivers.
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.
Moreover it s tough and flexible thereby attains high output.
