Sennheiser AMBEO Subwoofer for immersive home audio

The Sennheiser AMBEO Subwoofer is a dedicated low-frequency speaker designed for home cinema and music listening. It uses an 8-inch high-end woofer driven by a 350W Class D amplifier to produce deep bass down to 27 Hz. AMBEO virtualisation technology creates a realistic 3D surround sound experience from a single unit.

Wireless multi-sub array and wired RCA integration

Up to four subwoofers can be connected wirelessly to a compatible Sennheiser Soundbar Plus using multi-sub array technology for scaled bass performance. Each unit can be calibrated individually for optimal output. A wired mono RCA input is also provided for connection to a Sennheiser Soundbar Max, offering a physical link where wireless is not preferred.

Automated room calibration and app control

A built-in far-field microphone scans the room acoustics to perform automated self-calibration, tailoring the 3D sound profile to the specific space. Day-to-day operation is handled through the Smart Control App, which provides access to equaliser settings and audio adjustments. Regular firmware updates maintain compatibility and add features over the product lifespan.

Questions about this item

Which connection method should I choose between wireless and wired?

Wireless multi‑sub array technology lets you link up to four subwoofers to a Sennheiser Soundbar Plus without cables, while the mono RCA input provides a wired link to a Sennheiser Soundbar Max.

What does the 27 Hz figure mean for real‑world listening?

The sealed 8‑inch woofer driven by the 350W Class D amplifier reproduces bass down to 27 Hz, so low‑frequency effects like explosions or pipe‑organ notes are felt as well as heard.

How does the RCA input limit the signal chain?

The mono RCA jack accepts a single‑channel line‑level feed from a Soundbar Max, so only one subwoofer can be connected per RCA output and no wireless pairing is used for that link.
