Speaker mounting rings for BMW cars are used for precise, stable and professional installation of new speakers in factory mounting positions without the need to intervene in the body or interior. In this category you will find both plastic mounting rings , which are characterized by easy installation and resistance to moisture, and MDF rings , which, thanks to their rigidity and acoustic properties, provide better sound performance and effectively dampen unwanted resonances. All washers are designed with the specifics of BMW cars in mind and allow for quick and safe replacement of speakers without the need for modifications to the door panels. Rings of various depths and diameters are available (most often 130 mm, 165 mm or 200 mm) for use in front and rear doors. Whether you choose plastic or MDF, you will get a mounting solution that ensures a firm hold of the speaker and supports high-quality sound performance.
