The Denon DSW-1H Subwoofer (Open Box) adds powerful, deep bass to the Denon DHT-S716H soundbar bringing that suspenseful rumble and heightened immersion to all your favourite movies and shows. Easily pair the wireless subwoofer to the Denon soundbar through a Wi-Fi connection and start enjoying more dynamic content.

With dual custom 5.25 inch drivers powered by 70W of Class D high power amplification, the DSW-1H subwoofer delivers clear, room-filling bass, using DSP algorithms to provide optimised low frequency response across the whole dynamic range.

Featuring built-in HEOS technology, the subwoofer combines easily with other HEOS-enabled products so you can create your own experience complete with thundering bass. The DSW-1H sub can be added to the DHT-S716H soundbar for a 3.1 home cinema system, or with two HEOS speakers for a 2.1 system, ideal for music. Combining both, with two HEOS speakers as rear surrounds and the soundbar, create an immersive 5.1 system using the subwoofer without any need for connecting cables.

Use the HEOS app to control the subwoofer’s advanced settings, including volume, low pass filter and phase to get everything sounding just right. With a unique, stylish design, the subwoofer can be placed anywhere in the room thanks to its easy wireless connection.
