Speaker-cover cloth must protect drivers visually without materially compromising sound, making it different from ordinary upholstery.
Match material to the actual application
Evaluate open, stable polyester structures and seek acoustic transmission measurements for the exact material. When requesting samples, describe the expected conditions of storage, handling, washing and customer use. Even two fabrics with the same polyester content can differ substantially in stability, surface friction and finishing.
Critical design and sourcing risks
Dense coatings, foam backing or heavy decoration can attenuate frequencies and alter perceived output. Confirm whether the required performance comes from a yarn, construction, finish, coating or a completed product feature; these distinctions affect pricing and the tests needed.
Construction details that affect reliability
Mount the candidate fabric with the final tension and frame geometry, then compare frequency response against an uncovered reference. Include fastening components, linings and seam geometry in the sample approval. A swatch may behave well while a stitched product fails at an edge or closure.
What to test before a bulk order
Check fabric stretch, lightfastness, abrasion and edge attachment after installation. Keep one reference sample with its fabric lot number, finished width and measured weight. Record the test conditions so incoming rolls can be checked consistently.
Procurement decision
Do not market ordinary knitted fabric as acoustically transparent without tested evidence. Request both the fabric specifications and a finished prototype. The lowest price per kilogram may not be economical if rejects, cutting loss or shortened service life are high.
Buyer checklist
- Confirm fibre blend, finished GSM, width and colour standard.
- Document the intended use and any required third-party testing.
- Check seams, trims, fasteners and wash performance on a finished sample.
- Compare actual usable yield, quality consistency and replacement availability.
