The Bose Bass Module 500 makes the bass of your favorite movies, series, or games sound extra deep. This 5.2-inch subwoofer is especially made for the Bose SoundTouch 500 soundbar. You can connect the bass to AC power and connect both devices to each other with a wireless connection. This way, the clear sound of the soundbar is complemented with a powerful bass reproduction. The compact design is only 25 centimeters high and wide. This means you can easily store the bass speaker in your room.
