December 15, 2021

Press Release

Polk Audio today announced its first Dolby Atmos sound bar system, the Signa S4, which features seven drivers, including two upward-firing speakers, that deliver powerful 3D surround sound. When paired with the included wireless subwoofer, the complete sound bar system provides a thunderous, crystal clear, cinematic surround sound experience at a great value.

“The Polk Signa S4 sound bar delivers superb Dolby Atmos surround sound that enhances everything from movie special effects to music ambiance to games." said Frank Sterns, president of Polk Audio. "Whether you’re getting a sound bar for the first time, or looking to upgrade to Dolby Atmos, the Signa S4 delivers on Polk's promise of exceptional sound quality coupled with great value.”  Sterns added.

More Realistic Surround Sound

The Signa S4 uses two upward-firing speakers that deliver Dolby Atmos height channels to create lifelike overhead sound, perfect for experiencing the latest blockbuster releases and immersive Dolby Atmos music or gaming. The Signa S4 can also up-mix non-Atmos rendering height, surround and center channels to create a virtual Atmos experience.

In addition, the Signa S4’s advanced seven-speaker array features a discrete center channel and optimized left/right tweeters and woofers for a huge sound stage. The dedicated center channel is paired with Polk’s patented VoiceAdjust™ technology, to dramatically improve dialogue intelligibility and ensure listeners don't miss a word during intense action scenes, sporting events and especially when viewing at lower volumes, such as night-time. 

Effortless Bass

The Signa S4 includes a powerful wireless subwoofer to provide Polk’s deep effortless bass. The subwoofer connects wirelessly to the sound bar automatically on start-up and can be conveniently placed nearly anywhere in the room (within 33ft/10m). In addition, the Bass Adjust feature controls low frequency output on both the sound bar and subwoofer, generating an optimized blend and maximum impact at any desired level.

Customizable Sound

In addition to the sound customization provided by Polk VoiceAdjust and Bass Adjust, users will appreciate one-button access to presets that have been fine tuned for movie or music listening. In addition, Signa S4 offers Night Mode, which automatically attenuates bass output and accentuates dialogue clarity so users can avoid disturbing sleeping neighbors or family members during late-night binge-watching sessions.  

Easy Operation & Music Listening

The Signa S4 is incredibly easy to set up and use. With one simple connection via the included HDMI or optical cable (or aux-in for older TVs), the sound bar is ready to deliver the ultimate listening experience with even the latest 8K Ultra-HD TVs. Built-in HDMI eARC can pass through eight channels of uncompressed audio, delivering sonic excellence. For added convenience, the Signa S4 is pre-programmed to work with most TV remotes, and pairs effortlessly with mobile devices via Bluetooth to facilitate streaming. The low-profile design of the Signa S4 is ideally suited for any décor, and it can be wall-mounted for a sleek appearance.

Pricing and Availability

The Polk Audio Signa S4 Dolby Atmos sound bar system comes complete with HDMI and optical cables for effortless connectivity. The Signa S4 is available now, direct from PolkAudio.com or through authorized Polk resellers for an MSRP of $399 ($ U.S.).
