How are speakers being made?

• 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.
