A baffle loudspeaker is an open-diaphragm loudspeaker that enhances the radiation of sound power by surrounding the diaphragm with a large, typically wooden, plane baffle.

Key Points:

  1. Design:
  • Open-Diaphragm: The loudspeaker’s diaphragm is exposed and not enclosed in a cabinet.
  • Large Plane Baffle: The diaphragm is mounted on a large, flat surface (baffle) to improve sound radiation.
  1. Function:
  • Sound Enhancement: The baffle helps to prevent the sound waves produced by the back of the diaphragm from interfering with the waves from the front, reducing phase cancellation and enhancing overall sound quality.
  • Acoustic Short-Circuit Prevention: By separating the sound waves produced at the front and rear of the diaphragm, the baffle reduces the acoustic short-circuit, where low-frequency sound waves from the back cancel out those from the front.
  1. Material:
  • Typically Wood: The baffle is generally made of wood, which provides a sturdy and resonant structure.
  1. Applications:
  • Home Audio Systems: Used in high-fidelity home audio systems for improved sound quality.
  • Public Address Systems: Employed in PA systems to ensure clear and powerful sound projection.
  • Studio Monitors: Utilized in studio monitors for accurate sound reproduction.


A baffle loudspeaker is a type of loudspeaker that uses a large, flat baffle, typically made of wood, to enhance sound radiation by preventing acoustic short-circuiting. This design improves the clarity and power of the sound produced, making it suitable for various high-fidelity audio applications.
