Focal Integration IBUS 2.1 8inch 20cm Flat Active Subwoofer. Used but mint condition. This subwoofer is incredible, it has so much power out of such a small box. Sound quality is just amazing and the sheer amount of bass is next level. I was so happy with this subwoofer, but I recently got a car with a high end audio system built in so it’s time to say goodbye to the monster focal.
