  Made from Polyurethane, The CH6520 6. 5 inch car speakers provide a resilient and durable material that can offer great sound with the advantage of long lasting speakers .
  

  A substance called 'Polyurethane' and is categorized as a 'Polymer'. It is a resilient, flexible and durable manufactured material that can take the place of paint, cotton, rubber, metal or wood in thousands of applications across virtually all fields. It can be hard like fiberglass, squishy like upholstery foam, protective like varnish, bouncy like rubber or sticky like glue.

  In the specific case of our cones, this material allows for maximum flexibility that produces great sounding speakers lasting you a long, long time.

  
  
  
• Voice Coil -
  
  Our voice coils are able to withstand high temperatures yet maintain tts strength and fatigue properties. Making our voice coils with this material, gives our speakers the advantage of longer play times with lower weights
  
  Our speakers are capable of higher or elevated temperature strength and fatigue properties that will increase performance and efficiency of heavy duty play time through lower weight and higher operating temperatures.
  
  
  
• Surround -
  
  Rubber has the ability to endure much punishment without any sign of damage. It complements the whole structure of the speaker by allowing constant abuse where it is most needed, without the wear and tear .
  
  Up until about 30 years ago, foam surrounds tended to deteriorate more quickly, but due to recent advancements, the average life span of standard foam surrounds is about 8 to 16 years. New foam formulas last much longer and are a superior product for speaker drivers that need a large excursion (how much the cone needs to move back and forth). Foam keeps the cone centered and yields a high excursion. Foam is self damping (the ability to control undesirable movement of the speaker cone) and reduces its own standing waves. It is also very light and has a minimal effect on the motion of the cone. Foam can be mixed with other substances to produce different flex and strength properties.
  
  
  
• Tweeter -
  
  A Piezoelectric tweeter is more resistant to overloads and can be used without a crossover due to its electrical property >
  
  For a modern edge the best car speaker could be the high tech Mylar tweeter, as it generally has more ability for a wider variance of sound modifications and channel handling. Unlike paper cones, the Mylar has a higher rate of durability, as the cone is made of a plastic poly material, which does not rip or tear easily, under abnormal frequency changes.
