Audison BMW Series APBMW K4M Speaker Kit

APBMW K4M Kit | 100W Peak Power | 2-Way Component System | 4 Ohm | BMW Sound System Upgrade

The Audison APBMW K4M is a high-quality 2-way speaker kit engineered to upgrade OEM audio systems in BMW and MINI vehicles. Designed for precision and realism, the system creates a wide, three-dimensional soundstage while preserving the original musical tone and detail.

The 100 mm (4-inch) midrange speaker features a water-repellent, pressed-paper cone—ideal for reproducing natural-sounding mids with low resonance. Its low-frequency response allows for a hi-pass cutoff between 150–200 Hz, enabling excellent mid-bass performance.

Paired with a 25 mm Tetolon dome tweeter, the system delivers extended and smooth high-frequency response. Optimized for off-axis performance, the tweeter enhances the soundstage, producing a realistic and immersive in-car listening experience.
