Audison APBMW S8-2.2 – 200 mm Underseat Subwoofer for BMW/Mini, 2 Ohm, 150 W RMS

The Audison APBMW S8-2.2 is a 200mm subwoofer specifically designed for BMW and Mini models for the underseat position. With 2 Ohms, 150 W continuous power, and 300 W peak power, it efficiently utilizes the existing installation space and delivers dry, deep frequencies from 40 to 500 Hz. The compact Neodymium motor keeps the installation depth low while ensuring control and efficiency.

Technical Highlights

• 200mm underseat driver with 2 Ohms for high output from common car hi-fi amplifiers
