The AMBEO Sub guarantees a breathtaking cinematic experience and, as you would expect from Sennheiser, is also excellent for listening to your favorite music. Our latest subwoofer delivers a compelling sound that gives you goosebumps. The sub is powered by Ambeo, a groundbreaking 3D sound technology developed in collaboration with the German research organization Fraunhofer IIS Institute. It provides extremely deep bass and offers the most natural sound you have ever experienced. With a design that matches its incredible sound quality, a sealed enclosure ensures audiophile bass down to 27 Hz, and an 8-inch high-quality patented woofer guarantees unparalleled bass. With Multi-UB-Array technology, you can connect up to four subwoofers to enhance bass performance and calibrate them individually for optimal sound, while the wireless connection ensures your room stays clean and tidy without the needed cables. The advanced self-calibration of the AMBEO Sub and the built-in microphone provide an extensive experience that brings out the best in your AMBEO Sub. Just plug it in, set it up, and enjoy.
