A pair of BLAM BMW hi-performance dedicated 200mm (8 inch) extra-flat underseat subwoofers. BMWs are very specific to equip, since they have very specific subwoofers under the front seats. These extra flat subwoofers are custom made to make the installation process faster and make the sound image more precise and clear. The BM200WN woofer has been designed specifically to mount in the original location. It replaces very advantageously the 165 mm woofers installed as standard in many models. It is compatible with the BMW Serie 1/3/5/6/7 and X1 / 3/5/6. 200 mm 8” extra flat underseat subwoofer for BMW. Power 120 W – RMS Power: 60 W. Frequency response: 40 Hz – 1 kHz. Impedance 2?
