  1. Listening to Kevlar By: Juan Gonzalez MEEN 3344

  2. Today, many speakers are being made using various types of materials. They can be made from treated paper, synthetics, or composites. Many companies are using Kevlar reinforced woofers to add strength and durability. They feature long interlaced aramid reinforced carbon graphite IMPP. This provides the strength and rigidity powerful bass requires. How are speakers being made?

  3. How Kevlar makes a difference? • Kevlar is a heat resistant and strong synthetic fiber. • It has good resistance to abrasion. • It has practically no melting point, degradation starts at 500°C.

  4. Factory Speaker Made of paper & foam Can be easily torn Don’t handle high amount of power Foam surround dries and cracks in high heat Kevlar Reinforced Speaker Made of Kevlar and other durable materials Greater resistance to abrasion Handles a much greater amount of power Won’t dry and crack like factory speaker Difference between factory speaker and aftermarket speaker with Kevlar.
