Universal MDF speaker rings are a great choice for anyone who wants to achieve high-quality sound, a stable fit and a professional result when installing new car speakers, regardless of the specific vehicle model. They are made of solid wood fiber material (Medium Density Fibreboard), which is characterized by excellent acoustic properties - it eliminates resonance, dampens vibrations and improves the overall sound performance. Thanks to the universal design, these washers can be easily adapted to various types of mounting, depths and diameters of speakers, most often 130 mm, 165 mm or 200 mm. They are suitable for mounting in front and rear doors, in upholstery, or on custom-made installation surfaces. Universal MDF frames are an ideal solution for both home car audio enthusiasts and professionals who require flexibility, accuracy and a high level of sound quality. Thanks to their variability, they enable clean and solid installation of speakers in almost any car.
