Audison has engineered a 200 mm shallow-frame underseat woofer for BMW and MINI. These can be used as replacements with OEM amplification, but best results are attained when used in a system upgrade that includes Audison Forza bit amplifiers and BMW integration harnesses.
Audison R&D used an injection-molded frame with graphite fibers (to increase rigidity), and a neodymium magnet for a smaller size (important with the inverted-magnet configuration). The 2”/50mm voice coil is the largest used in any BMW replacement woofer. The inverted-magnet design has a top vent in the pole, to extend thermal performance and power handling. The acoustically-transparent fabric cover keeps debris off of the speaker cone, which prevents distorted sound in the under-seat location.
The APSBMW S8-2.2 2Ω woofer allows more power to be delivered from a single amplifier channel. In many higher-performance BMW systems, the underseat woofer is used on a single set of channels as midbass drivers with purposefully-limited sub-bass extension (while a larger subwoofer does its work in the trunk playing the lowest notes). The APSBMW S8-2 is also perfect for this midbass application.

To maximize performance while minimizing bulk and weight.
To increase listening engagement, through powerful and crisp low frequencies, exploiting the acoustic load provided by the factory box.
For a considerable power dissipation and stability even during high excursions.
For OEM placements.
In combination with AP 8.9 bit in active multi-amplification.
