Polk Audio has announced its first Dolby Atmos sound bar system, the Signa S4, comprising seven drivers, two of which are upward-firing. The complete sound bar system, priced at $399,  includes a wireless subwoofer which, when paired with the bar, promises to provide “thunderous, crystal clear, cinematic surround sound”.

“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.

As well as providing an immersive audio soundstage, the system can also up-mix non-Atmos content enabling a virtual Atmos soundfield. The seven-speaker array includes a discrete center channel, “optimized” left/right tweeters and in-built woofers. The center is paired with Polk’s patented VoiceAdjust tech to improve dialogue intelligibility in action scenes and at low night-time levels. The included subwoofer can be placed within 33ft of the bar anywhere in the room, and uses a Bass Adjust feature for maximum impact at desired levels.

As well as one-button access to music and movie presets – including a Night Mode to avoid disturbing neighbors – the Signa S4 has HDMI 2.1, eARC (passing through eight channels of audio) and optical connections. The system is pre-programmed to work with most TV remotes, and pairs with mobile devices via Bluetooth for streaming. The system promotes a low-profile, sleek design and can be wall mounted. HDMI and optical cables are included. The Signa S4 is available now from Polk Audio or authorized resellers.
