Product Details

Rear Speaker Upgrade for BMW 1 Series

The two-way APBMW K4M kit creates a three-dimensional sound stage and give the musical message the essential timbre accuracy. 

The 100 mm (4″) midrange is provided with a water-repellent pressed-paper cone, a material providing natural sound. It features a low resonance frequency that allows hi-pass cut-off in the 150-200 Hz range for an excellent mid-low reproduction. 

The 25 mm coil and Tetolon dome tweeter features a great extension on both medium and high frequencies and is optimized for off-axis output, for an extended sound stage in the three dimensions, that amplifies the perception of reality in the car cabin.
