Polk Audio Signa S4

The Polk Audio Signa S4 Soundbar with Wireless Subwoofer delivers powerful Dolby Atmos surround sound and crystal clear dialogue at an unbeatable price.

The soundbar is equipped with seven speakers, including two that create virtual height channels, which provide powerful 3D surround sound. Combined with the included wireless subwoofer, the soundbar delivers stunning, crystal-clear, cinematic surround sound at a great price.

The Polk Audio Signa S4 uses two speakers that work as height channels to create the Dolby Atmos effect and realistic sound above you, which is an absolute must when watching the latest blockbusters, the latest music or games with Dolby Atmos. The Signa S4, with its height and center channels, can create a virtual Dolby atmosphere even in non-Dolby Atmos content.

In addition, the Polk Audio Signa S4 features a seven-speaker package including a dedicated center channel, as well as optimized left and right tweeters and woofers for a wide soundstage. The dedicated center channel provides Polk's patented VoiceAdjust technology, which greatly improves dialogue intelligibility and ensures listeners don't miss a word during intense scenes in movies, sports programs, and especially when watching at low volumes such as at night.

The Polk audio Signa S4 comes with a powerful wireless subwoofer that delivers deep and light bass. The subwoofer connects wirelessly to the soundbar automatically upon startup and can be conveniently placed almost anywhere in the room (within 10m of the soundbar). In addition, bass control is available on both the soundbar and subwoofer for optimized sound and maximum performance at any volume level.

In addition to sound customization provided by the Polk VoiceAdjust and Bass Adjust systems, users will appreciate one-button access to preset equalizer settings that are ideal for watching movies or listening to music. In addition, the Polk Audio Signa S4 features a Night Mode that automatically attenuates low frequencies while enhancing dialogue intelligibility so users can avoid disturbing sleeping neighbors or family members during night sessions.

The Polk Audio Signa S4 is incredibly easy to set up and use. With just one connection of the included HDMI cable or optical cable (or aux-in for older TVs), the soundbar is ready to deliver unrivaled sound quality even with the latest 8K Ultra-HD TVs. Dolby Atmos can be input through the built-in HDMI eARC for superior sound quality. For added convenience, the Polk Audio Signa S4 is programmed to work with most modern TV remote controls and easily pairs with mobile devices via Bluetooth for streaming music. The low profile design of the Polk Audio Signa S4 is perfect for any interior and it can be well integrated into any room design.
