Polk Audio Signa S4: Soundbar with Dolby Atmos

The Signa S4 is Polk’s first Dolby Atmos soundbar, featuring seven built-in drivers and a wireless subwoofer.

In addition to the upward firing drivers, the S4 features a discrete center channel and optimized left/right tweeters and woofers. The center channel works in conjunction with the patented Polk Voice Adjust technology to improve intelligibility. In addition, the Signa S4 emulates Dolby Atmos sound as well as surround and center channels from non-spatial recordings.

The included wireless subwoofer can be connected up to 10m away for an optimized bass combination. There are additional preset modes for movies or music, as well as a night mode that automatically attenuates low frequencies and emphasizes the clarity of dialogue.

HDMI and optical cables are included with the Signa S4, and Dolby Atmos is also possible with built-in eARC support. You can listen to audio from compatible devices via Bluetooth. In addition, the S4 is pre-programmed to work with most TV remote controls, and its low-profile, fabric-covered design blends well with just about any decor. In addition to the desktop version, the Polk Audio Signa S4 Dolby Atmos soundbar can also be placed on the wall.
