The Sennheiser Ambeo Sub wireless subwoofer pairs with AMBEO series soundbars. Its sealed enclosure and 8-inch woofer support a frequency response of 27–80 Hz, while the Class D amplifier delivers 350 W RMS. Room self-calibration uses the built-in microphone, and digital processing compensates for adverse room characteristics.

Up to four AMBEO Subs can be connected to one soundbar. Wireless transmission uses Bluetooth 5.2 Low Energy, and a mono RCA input is available for wired connections.
