The Audison Prima APBMW S8-4.2 Subwoofer has been designed with electro-acoustic parameters to maximize performance from 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 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.
Difference between S8-4 and new S8-4.2
The main difference is the new S8-2.2 has new depth dimensions and slightly altered Electro-Acoustic Parameters. Here are some comparison illustrations below.

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. You can choose between S8-2.2 with 2 ohm impedance and S8-4.2 with 4 ohm impedance for improved system composition versatility.
In fact, in the mid-high passive filtered system configuration, with the crossover provided, 4 of the 8-channels of the Prima AP 8.9 bit can be configured in bridge mode delivering 130W rms to each S8-4.2 installed under the seat. The Neodymium magnet used on S8-4.2 and S8-2.2 allows for greater power and control than ferrite, while maintaining the depth of installation unaltered.
