Sennheiser AMBEO Sub 8" Wireless Powered Subwoofer 350W

The Sennheiser AMBEO Sub is a premium powered subwoofer designed to deliver deep, powerful and precisely controlled bass for immersive home theater entertainment. Featuring a proprietary 8-inch long-throw woofer, a 350-watt RMS Class D amplifier and advanced AMBEO audio processing technology, it brings cinematic low-frequency impact to movies, music and gaming.

Developed with technology co-created alongside the Fraunhofer IIS Institute, the AMBEO Sub combines sophisticated digital signal processing with a sealed acoustic enclosure for accurate bass reproduction extending down to 27Hz. Automatic room calibration adapts its performance to the listening environment, while the Sennheiser Smart Control app provides convenient access to sound adjustments and equalizer settings.

Deep, Powerful Bass Down to 27Hz

The AMBEO Sub delivers rich, room-filling low frequencies that add weight and realism to movie soundtracks, music and entertainment. Its proprietary 8-inch long-throw cellulose cone driver is engineered for controlled excursion and accurate bass reproduction.

With a frequency response extending from 27Hz to 80Hz, the AMBEO Sub reproduces deep cinematic effects, powerful musical bass lines and subtle low-frequency details that enhance the overall listening experience.

350-Watt Class D Amplification

A built-in 350-watt RMS Class D amplifier provides the power and control required to drive the high-performance 8-inch woofer. The efficient amplifier design works with advanced digital audio processing to deliver dynamic bass output while maintaining clarity and precision.

Sealed Acoustic Enclosure

The AMBEO Sub features a closed acoustic enclosure designed to produce tight, controlled bass without the port noise associated with conventional bass-reflex designs.

This sealed construction helps maintain accurate low-frequency reproduction, making the subwoofer suitable for both cinematic effects and demanding music playback.

Advanced AMBEO Audio Technology

AMBEO audio technology, developed in collaboration with Fraunhofer IIS, enhances the low-frequency foundation of compatible immersive sound systems. Sophisticated audio processing helps create a more realistic and engaging listening experience, allowing bass effects to be both heard and felt.

Automatic Room Calibration

Automatic self-calibration analyzes the acoustic characteristics of the listening environment and adjusts subwoofer performance accordingly. This helps optimize bass reproduction for different room sizes, layouts and placement positions.

The calibration system works to deliver balanced low-frequency performance without requiring extensive manual adjustments.

Connect Up to Four AMBEO Subwoofers

Advanced multi-subwoofer array technology allows up to four compatible AMBEO Sub units to be connected wirelessly to a supported AMBEO Soundbar system.

Each subwoofer can be calibrated individually, providing greater flexibility for distributing bass throughout larger rooms and improving low-frequency consistency across multiple listening positions.

Wireless and Wired AMBEO Soundbar Integration

The AMBEO Sub supports wireless connectivity with the Sennheiser AMBEO Soundbar Plus, providing a convenient installation without requiring an audio cable between the soundbar and subwoofer.

For the AMBEO Soundbar Max, the subwoofer connects through the soundbar's dedicated subwoofer output using a wired RCA connection.

This flexible connectivity allows the AMBEO Sub to complement different compatible Sennheiser home theater configurations.

Smart Control App

The Sennheiser Smart Control app provides intuitive access to compatible audio settings, equalization and system configuration. Users can personalize bass performance and manage their listening experience from a compatible mobile device.
