The 2mm metal speaker grille mesh with small round holes is designed for maximum driver protection without compromising acoustic transparency. Its uniform perforations enhance sound clarity and ensure consistent airflow.
A Tokyo-based hi-fi workshop used 2mm stainless steel mesh with 1–2mm round holes for a custom bookshelf speaker line. After referencing the Audio Engineering Society Journal, they selected this mesh for its balance of strength, fine protection, and acoustic neutrality.
The result was a line of speakers that achieved both improved durability and pristine sound reproduction.
