Polk debuts (very affordable) Dolby Atmos soundbar

US Hi-Fi outfit Polk Audio has unveiled announced its first Dolby Atmos sound bar system, the Signa S4 - at a price that undercuts many of its rivals.

The new Bluetooth enabled soundbar and wireless subwoofer combo features seven drivers, including two upward-firing speakers to deliver Dolby Atmos height channels. The Signa S4 will also up-mix non-Dolby Atmos rendering height, surround and centre channels to create a virtual Atmos experience.

The Signa S4’s seven-speaker array features a discrete centre channel and optimized left/right tweeters for a widesound stage. The dedicated centre channel is paired with Polk’s patented VoiceAdjust technology, to improve dialogue intelligibility, said to be particularly useful when viewing at lower volumes.

The partnering subwoofer has a Bass Adjust feature that controls low frequency output on both the sound bar and subwoofer.

In addition to Polk Voice Adjust and Bass Adjust customisation, users will appreciate the system incorporates one-button access movie and music presets, while a Night Mode attenuates bass output and accentuates dialogue clarit, to avoid disturbing family members during late-night binge-watching sessions.

Connectivity includes high-spec HDMI with eARC, optical digital audio and analogue stereo. To enhance ease of use, the Signa S4 is pre-programmed to work with most TV remotes, and pairs with mobile devices via Bluetooth for easy music streaming.

Available now, the Polk Audio Signa S4 retails for a competitive £329.
