Summary

• FINECone can be used for significant analysis and
  design of the acoustical components in
  loudspeakers
• FINECone can accurately simulate and predict
  break-up in loudspeakers.
• FINECone is a valuable design tool for
  loudspeaker engineers
• FINECone can find the problems in your speakers
  and can help you find the solution
