APBMW K4EKit | 100 W Peak Power | Kit 2 way 4 ohm | BMW Upgrade
The two-way APBMW K4E kit creates a three-dimensional sound stage and give the musical message the essential timbre accuracy. The 100 mm (4 in.) 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.
