The material of the speaker cabinet is related to the vibration factor, and the material is crucial to the sound quality. The box materials are wood, plastic, and metal, and a few use stone and cement materials.

Wooden boxes are usually divided into MDF (also known as medium fiberboard), adhesive board, and solid wood materials. Solid wood speakers are generally more expensive, and not all woods can be used as solid wood speaker materials. Most brand speakers use MDF, and a few flagship products use solid wood materials. Plywood is the worst material for wooden speakers.

The advantages of plastic materials: low cost, easy to form, and can be processed into any shape. Disadvantages: The sound quality is relatively poor.

The advantages of wooden materials: small vibration and relatively good sound quality. Disadvantages: The process is complicated, and it is afraid of water and moisture.

Advantages of metal materials: easy to form and gorgeous appearance. Disadvantages: only suitable for mid-range and high-pitched speakers, not low-frequency speakers.

The advantages of stone and cement material boxes: low vibration, especially suitable for low-frequency speakers such as subwoofers. Disadvantages: Too bulky, difficult to shape, complex process, and the stone box cost is high.

The radiation of speakers is not large, and its radiation problem is generally not considered.
