Front Door Speakers & Under Seat Subwoofer Upgrade for BMW 1 Series

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″) 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. 

Subwoofers have been designed with electro-acoustic parameters that maximize performance for the factory box available below the seats. The ABS plastic basket, reinforced with fiberglass, and the acoustic structure featuring a front magnet, provide for a minimal installation depth for a perfect compatibility with the whole range. Two 5 mm polyurethane gaskets, supplied, allow the subwoofer to fit perfectly to the box, decoupling it from vibration. 

The 200 mm (8″) APBMW S subwoofers allow a “direct replacement” of the OEM speakers underneath the front seats, making the most of the factory acoustic load and generating deep and crisp low frequencies.
