Poly Speaker Dust Cap | 3"

This 3-inch polypropylene dust cap offers a reliable solution for restoring both the appearance and acoustic performance of your loudspeaker drivers. Precision-moulded from durable polypropylene, it is designed to replace damaged or missing dust caps on woofers, midrange drivers, and full-range units, helping to prevent debris from entering the voice coil gap while maintaining the cone’s structural integrity. Ideal for DIY repair projects, refurbishing vintage speakers, or upgrading entry-level audio systems, this cap ensures that your drivers continue to deliver clear, undistorted sound. The cap measures 76 mm in outer diameter, making it compatible with a wide range of standard 3-inch driver frames. Its lightweight yet rigid polypropylene construction minimises mass loading on the cone, preserving the driver’s original frequency response and transient behaviour. The smooth, low-profile dome shape aids in consistent dispersion of high frequencies, while the material’s inherent damping properties reduce unwanted resonances. Whether you are restoring a cherished pair of loudspeakers or building a custom enclosure, this dust cap provides a straightforward, cost-effective repair that extends the life of your audio components.
