MDF speaker rings for BMW cars are designed for precise, solid and acoustically optimized installation of aftermarket speakers in original mounting positions without the need for modifications to door panels or other interior parts. They are made of high-quality MDF (Medium Density Fibreboard), which is characterized by high rigidity, excellent vibration damping and long service life. The offer includes CNC milled MDF frames designed for BMW 1, 3, 5, 7, X5, X6 series and other models, especially for speakers with a diameter of 165 mm. All rings are protected against moisture by impregnation and painting to provide reliable performance even in more demanding conditions. They are suitable for both front and rear doors, or other specific locations depending on the model. By using them, you will not only get a clean and stable sound without resonances, but also a simple and professional installation. For installations in areas with higher humidity, Ahifi recommends considering the use of plastic adapters as an alternative.
