The Audison APBMW K4M is a two-way component speaker kit specifically designed for BMW and MINI vehicles equipped with factory two-way audio systems. This set allows you to upgrade your car's sound without modifying the original interior, as it includes plug-and-play connectors and extension cables for a straightforward installation. The 100 mm woofers feature a water-repellent pressed-paper cone and a fiberglass voice coil, ensuring durability and consistent performance even in humid conditions. These are supported by 29 mm tweeters with Tetolon coils, which are optimized for better sound dispersion within the cabin. Built for efficiency and clarity, the system utilizes neodymium magnets and aluminium die-cast baskets to keep the components lightweight yet sturdy. Each woofer handles 50 W of continuous power and can reach peaks of 100 W, while the inline high-pass crossovers allow you to adjust the tweeter level between -3 dB and 0 dB to suit your listening preference. The kit comes complete with tweeter supports for original placement and removable motor covers for damping, making it a practical choice for owners who want a cleaner, more detailed audio experience while maintaining their vehicle's factory look.
